Question

If the probability of rain is 0.05 ,what is the probility of no rain ?

Answer 1

That would be 0.95.

All percantages must add up to 100%, or 1.00

Therefore, 1.00 - 0.05 gives you your probability of no rain, 0.95, or 95%

Answer 2

the probability of no rain is = 1-probability of rain
1-0.05=.95 is probability of rain
