Question

A weather report indicates that the chance of rain over the next three days is 80%, 20%, and 30% respectively. What is the probability that it will rain on all 3 days?

A. 0.024
B. 0.48
C. 0.6
D. 0.12

Answer 1

To find the probability of rain on all three days, multiply the probabilities of rain on each day.

Step-by-step explanation:

To find the probability that it will rain on all three days, we need to multiply the probabilities of rain on each day. The probability of rain on the first day is 80% (or 0.80), on the second day is 20% (or 0.20), and on the third day is 30% (or 0.30). So the probability of rain on all three days is 0.80 x 0.20 x 0.30 = 0.048, which is equivalent to 0.048 or 4.8%.

Therefore, the correct answer is option A. 0.024.
