Question

what will be probability of not getting rain when the probability of getting rain is 0.76

Answer 1

P(not raining) = 1 - P( chances of raining)

= 1–0.76

P(not raining) = 0.24

Answer 2

Denote probability of getting rain with P [E] and not getting rain with P [F]  As P [E]= 0.76 P [F]= ?   So; P (E)+ P (F)=1 0.76+ P (F)=1 P (F)=1-0.76 P (F)= 0.24
