Question

Warren flipped a coin and rolled a 20-sided die. What is the probability that his coin landed on tails and his die rolled a factor of 20? Write your answer as a simplified fraction.

Answer 1

1/40

Explanation:

The probability of a coin landing on tails is 1/2.

The probability of his die rolling a factor of 20 is 1/20

So 1/2 x 1/20 = 1/40
