Question

What's the probability of rolling a number less than 5 and a head when rolling a die and then tossing a coin?

Answer 1

D. 1/3.

Explanation:

Probability(Rolling a number < 5) = 2/3 and

probability( Getting a head) = 1/2

The required probability , since the 2 events are independent is the product of the above = 2/3 * 1/2 = 1/3.

Answer 2

`|\Omega|=6\cdot2=12\\|A|=4\cdot1=4\\\\P(A)=(4)/(12)=(1)/(3)`
