Question

A letter from the word geometry is chosen & then a dice is rolled. What's the probability that an "E" was chosen and then an even number was rolled?

Answer 1

1/8 or 12.5%

Explanation:

The word "geometry" has 8 letters, 2 of which are "e".

A dice has 6 sides, 3 of which are even numbers.

The probability of both events is:

P(A and B) = P(A) × P(B)

P(A and B) = 2/8 × 3/6

P(A and B) = 1/8

The probability is 1/8, or 12.5%.
