You can put this solution on YOUR website! The probability of rain is 20% on Friday,10% on Saturday,And 60% on Sunday.What is the probability that there is no rain on any of these three days?(To the nearest tenth of a percent).
------------
P(no rain on Friday) = 0.8
P(no rain on Saturday) = 0.9
P(no rain on Sunday) = 0.4
-------------------------------
Assuming the rain on each day is independent,
P(no rain on F or S or S) = 0.8*0.9*0.4 = 0.288 or 28.8%
