Question

If the probability of happening of an event A is 0.46. What will be the probability of not happening of the event A?

Sum

Solution

P(A) = 0.46

Let P(B) be the probability of not happening of event A

We know,

P(A) + P(B) = 1

P(B) = 1 – P(A)

P(B) = 1 – 0.46

P(B) = 0.54

Hence the probability of not happening of event A is 0.54
