Answer:
0.815
Step-by-step explanation:
Each year, on January 1st, there are only two possible outcomes. Either it snows, or it does not snow. The sum of the probabilities of these events is 100% = 1.
In this question:
0.185 probability of snow on January 1.
p probability of not snowing on January 1
0.185 + p = 1
p = 1 - 0.185
p = 0.815
The answer is 0.815
