Answer 2

Answer:

1. A coin is tossed twice

So the total number of possible outcomes = 4

Let A be the event that of getting a head

Then

The number of possible outcomes for the event A is = 3

So the required probability = 3/4

2. If P(E)= 0.05

Then the probability of getting not E

= P(E')

= 1-P(E)

= 1 - 0.05

= 0.95
