<PRE><B>Question 764078</B>
The odds of rain in June are 13:7. If rain on successive days is independent 
a.Find the probability that it will rain
P(rain) = 13/(13+7) = 13/20
-----------------------------------
b. Find the probability that it will rain in 3 days in a row
P(rain for 3) = (13/20)^3 = 0.2746
