Question

There is a 20% chance of snow on Tuesday and a 30% chance of snow on Wednesday. What is the probability that it willnotsnow on either day? Express your answer as a percent.

Answer 1

56%

Explanation:

The probability of snow on Tuesday is 20%, which means the probability of no snow on Tuesday is 100% - 20% = 80%.

Similarly, the probability of snow on Wednesday is 30%, which means the probability of no snow on Wednesday is 100% - 30% = 70%.

The probability that it will not snow on either day is the product of the probabilities of no snow on Tuesday and no snow on Wednesday:

(80%)(70%) = 56%

So the probability that it will not snow on either day is 56%.
