tutor3 : Hello Student, May I help you with your Math problems? student : In a certain town in Illinois, it rained on 148 out of the 365 days last year. 22 of those days were Wednesdays, and 20 of those days were Saturdays. Suppose it was raining at noon on a Wednesday. What is the probability that it was sunny 60 hours later? tutor3 : Please wait, we are helping other students tutor3 : see 60 hours later saturday comes.so we have to find the probability that it doesnot rain on a saturday. tutor3 : to do that we calculate the probability of rain in saturday = .148 . thus probability of no rain on saturady is = 1- 0.148 = 0.852 student : ok thx
