Question

if probability of having rain on a certain day is 2/5, then find the probability of not having rain on that day



EXPLAIN IT : ​

Answer 1

Given:

The probability of having rain on a certain day=2/5

To find:

Probability of not having rain on that day

Solution:

Let A be the Probability of having the rain on that day

so A' be the probability of not having rain on that particular day

P(A) + P(A') = 1

2/5 + P(A') =1

P(A') = 1 - 2/5

P(A') = (5-2)/5

P(A') = 3/5

So the probability of not raining on that particular day is 3/5.
