Question

A single twenty-sided die is rolled twice. Find the probability of rolling a number less than 15 and rolling an even number.

Answer 1

The probability of rolling a number less than 15 and rolling an even number is;  7/20

What is probability of rolling a dice?

We are told that the single die has 20 sides.

There are 14 numbers less than 15. Thus;

On the first roll, probability of rolling a number less than 15 is 14/20.

Now, there are 10 even numbers in a 20 side die. Thus, probability of rolling an even number on the second roll is; 10/20

Thus;

probability of rolling a number less than 15 and rolling an even number = 14/20 * 10/20 = 7/20
