The probability that in a given year it will not snow on January 1st will be P = 0.915.
What is probability?
Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Since the total probability is always equal to 1 if the probability of happening of an event is given then the probability of not happening of an event will be determined by subtracting it from one.
The probability of not any snowfall will be calculated as:-
P = 1 - 0.315
P = 0.615
Therefore the probability that in a given year it will not snow on January 1st will be P = 0.915.
