Question

Suppose the weather forecast calls for a "60% chance of rain" each day for the next 3 days. What is the probability that it will NOT rain during the next 3 days? Assume that whether it rains each day is an independent event. Round your answer to 2 places after the decimal point.

Answer 1

Probability that it will rain on a given day is 0.6

For next 3 days, probability that there will be no rain = (1 - 0.6) * (1 - 0.6) * (1 - 0.6)

= 0.4 * 0.4 * 0.4

= 0.064

i.e. 0.06
