Chapter 0.3, Problem 4E

To determine

To find Probability of outcome where number on dice is Prime.

Answer to Problem 4E

  $P=\frac{1}{2}$

Explanation of Solution

Given Information: A die is rolled

Formula Used : $P=\frac{PossibleOutcomes}{TotalOutcomes}$

Calculation:

When a die is rolled the total number of outcomes is 6.

To find the probability of outcome where number is prime, the possible outcomes will be 3 i.e. 2, 3 and 5.

  $P\left(prime\right)=\frac{PossibleOutcomes}{TotalOutcomes}$

So-

  $P=\frac{3}{6}$

Hence the final answer is,

  $P=\frac{1}{2}$
