0277
O 2/9​

Answer 1

Given :

A bag contains 15 balls numbered 1 to 15.

To find :

Find the probability of drawing a prime number.

Solution :

As there are 15 balls numbered 1 to 15, there are fifteen possibilities drawing a for ball.

Let A be an event prime numbered ball favourable outcomes for an event A are six I.e. 2 , 3 , 5 , 7 , 11 , 13

∴ Probability of drawing a prime numbered ball,

➸ p(A) = Favourable outcomes for an eventA / Total possible outcomes for an experiment

⇛ 6/15

⇛ 2/5
