Question

17. The probability of it raining today is 30%. What is the probability that it will NOT rain? *

Answer 1

Given,

P(A) = 30/100

To find,

P(not A)

Solution,

The probability that it will not rain is 70/100.

We can simply find the probability of not raining by using the relation,

P(A) + P(not A) = 1

          P( not A ) = 1-P(A)

          P(not A) = 1-30/100

           P(not A) = 70/100

Hence, the probability that it will not rain is 70/100.
