Step-by-step explanation:

The probability that it is a prime number is

A={2,3,5,7,11,13,17,19,23,29}

P(A) = Number of favourable outcomes / Total number of possible outcomes

= 10/30

= 1/3

Answer 2

Favourable outcomes are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29.

p(E) = number of favourable outcomes ÷ total number of outcomes

$= 10 \div 30 \\ = 1 \div 3$

therefore probability is 1/3 (one by three).
