Answer :
Answer:
The experimental probability that it will not rain on any of the next 3 days is [tex]\frac{64}{125}[/tex].
Step-by-step explanation:
The probability of raining is 20%.
Hence, the probability that there will be no rain, is (100 - 20) = 80%.
The probability that there is no rain on the first day is [tex]\frac{80}{100} = \frac{4}{5}[/tex].
Similarly, for the second and third day the probability is [tex]\frac{4}{5}[/tex].
Hence, the required probability is [tex](\frac{4}{5}) ^{3} = \frac{64}{125}[/tex].
