Question

You have the numbers 1-24 written on a slip of paper if you choose one slip at random what is the probability that you Will Not select a number which is divisible by 3

Answer 1

Answer:

 $\frac{2}{3}$.

Step-by-step explanation:

Given : You have the numbers 1-24 written on a slip of paper if you choose one slip at random .

To find : what is the probability that you Will Not select a number which is divisible by 3.

Solution : We have given that numbers from 1 to 24

Numbers divisible by 3 area 3,6,9,12,15,18,21,24.

There are 8 numbers which are divisible by 3

So, numbers which are not divisible by 3 are 24 -8 =16.

Probability of number which are not divisible by 3 = $\frac{16}{24}$.

Probability of number which are not divisible by 3 = $\frac{2}{3}$.

Therefore,  $\frac{2}{3}$.

Answer 2

3,6,9,12,15,18,21,24 are div by 3. thats 8 numbers out of 24. 8/24=1/3. 3/3-1/3 is 2/3. 2/3=66.67%
