Question

You toss a coin and roll a number cube. What is P(heads and an even number)?

Answer 1

P(heads and an even number)= `25%`

Explanation:

The events are independent (the outcome of flipping thee coin has no effect on the outcome of rolling the die).
`rArr` P(head and an even number)`=`P(head)`xx`P(even number)

Assuming a fair coin and a fair die:
P(head)`=50%`
P(even number)`=50%` (since half the numbers on a die are even).

P(head and even number)`=50%xx50%=25%`
