Question

A dice is rolled, the. A day of the week is selected. What is the probability of getting a number greater than 4 then a day starting with the letter s

Answer 1

2/21.

Explanation:

Prob(Getting a number > 4) = 2/6 = 1/3. (that is a 5 or a 6)

Prob(selecting a day starting with s) = 2/7 ( that is a Saturday or a Sunday).

These 2 events are independent so we multiply the probabilties:

Answer is 1/3 * 2/7 = 2/21.
