The probability of the spinner landing on a multiple of three is 4/12 because the multiples of three are 3, 6, 9, 12.
ReplyDeletethe probabilty to land on a multiple of 3 is: 4/12. Because the spinner has 12 equal sections, i did 3,6,9,12 those are 4 multiples of 3, withing the number values of 1-12.(1-12 is the labels for the section) this is my answer.:)

there are the numbers 1-12 on a spinner. the multiplies of three are 3, 6, 9, and 12. This means that there are four multiplies of three in this case making the odds, 4/12.

It is a 3 out of 12 probabillity that Frieda will spin 3 because all sectors are equal. Also there is numbers 1-12 labeled on the spinner and there is only one of each number on the spinner.
ReplyDeleteThe theoretical probability of Frieda spinning a multiple of 3 on her first spin is 4 over 12, 2 over 6 or 1 third. There are 12 sections and the numbers 3, 6, 9 and 12 are all multiples of 3. The number of appropriate outcomes is 4 and the number of total outcomes is 12. So you get a 4 in 12 chance. You reduce the fraction to get 2 in 6 or 1 in 3. The experimental probability might be different.
ReplyDeletethe chance is 4 over 12 or 1 over 4 or 25% or 0.25.

Hi everyone,
ReplyDeleteThe probability of Frieda spinning a multiple of 3 on her first try is 4 out of 12. Nine, three, six and twelve are the four multiples of three. There are 12 sections, therefore, the probability of Frieda spinning a multiple of 3 on her first try is 4 out of 12, or one third.

Well, there are 12 sections, and Frieda wants multiples of 3, and 12÷3=4. There is a 4/12 chance of spinning a multiple of 3 first. I can also divide each the numerator and the denominator by 4 to get 1/3, which is also 33.333333…% and 0.333333…
ReplyDeleteI gues this is sorta ez i probz got it wrong anywayz its like if u have 1 to twelve then 3 6 9 and 12 are multiples of 3. there are 12 numbers so 4 out of 12
ReplyDeleteughhh i dunno if my post went up so again like the first time its 4 of 12 cuz 4 numbaz are multiples of 3
ReplyDeleteThe chances are 4 over 12. simple enough. ps i'm devon. please remember that!
ReplyDeleteThe probability will be 4 out of 12 because there are 4 multiples of three that are under 12 that is possible to spin.
ReplyDeletethe multiples of 3 from 1 to 12 through are:3,6,9,12 so the ansewr is four in 12
ReplyDeleteThe probabillity of Freida spinning a 3 is 1 out of 12 because all 12 sectors are equal and there is numbers 1-12 labled on the spinner. The spinner has 12 different numbers.
ReplyDeleteThe probability is 4/12 or 1/3. This is because, from one to twelve, there are the nubers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12. Out of these numbers, 3, 6, 9 and 12 are multiples of 3. I know this because i know my multiplication tables. Another way to check your answer would be to divide each number by 3. If you do this, you will find that only 3, 6, 9, and 12 divide evenly and without a remainder. My answer is 4/12. But, you can also say: 1/3, or 33.3%
ReplyDeleteThere are 4 multiples of 3 from 1 to 12. They are 3,6,9 and 12. (3 is a multiple of 3 because 3x1=3). Therefore the probability of spinning a multiple of 3 on your first turn is 4/12 or 1/3.
ReplyDelete1,2,3!,4,5,6!,7,8,9!,10,11,12!
ReplyDeletenumber than ! = a multiple of 3
4/12
The probability of her choosing a multiple of 3 is 4/12. I got this because i just counted the how many multiples of 3 there are in between 1 and 12 and just finding the percentage. My dad also made me do the hard and unnecisary way of figuring this out.
ReplyDeleteThe probability that she will spin a multiple of 3 is 4 out of 12. that is because is you look at all the numbers on the spinner (1,2,3,4,5,6,7,8,9,10,11,12) and you multiply 3 by one (3) and then look at the numbers, then you see it on the spinner it proves that there is one. you keep doing different multiples of 3 until one cannot be found on the spinner. Also incase you were wondering the four multiples are 3,6,9,12. sorry it is kinda complicated and that my spelling isn't the best. -Emily
ReplyDeleteI was thinking about this quesiton and that you might want the worded version of the probability like: unlikely, possible and all that jazz, so other than it being 4/12 it is also unlikely, but still possible to spin a multiple of 3. so just incase you needed that. -Emily (Sorry for spelling, grammar, punctuation and my weird explanatons)
ReplyDeleteShe has a 4/12 chance of spinning a multiple of 3 because there are 4 multiples of 3 on the spinner. Those multiples are 3, 6, 9 and 12.
ReplyDelete3, 6, 9...,12 which is 4...... I think it the answer is 4. 4 out of 12 or 1 out of 3........... 0.3333333333333333333333333333333......%
