The probability it will rain is 40% each day over a three-day period. what is the

probability it will rain at least one of the three days?

0.784

Step-by-step explanation:

let's work backward.

The probabilty it will rain each day is 40%, so probabilty of dry weather is 1 - 40% = 60%

Probability of dry weather 3 day = 0.6*0.6*0.6 = 0.216

Hence, probability it will rain at least one of the 3 days = 1 - 0.216 = 0.784
