Question 464124: Hi. I need help with a probability question. It's been a while since I've done this!
Here goes: If there is 60% chance it will rain on Saturday, a 60% chance it will rain on Sunday, and an 80% chance it will rain on Sunday when it rains on Saturday, what is the probability it will rain on the weekend?
Many thanks!

As i think that here to find the probability it will rain on both days i.e Saturday and Sunday.
probability = 60/100 * 80/100 = 48/100 i.e 48%

-------------------------------------------------------------------------
if you have to find the probability it will rain on either of two days.
probability that no rain on both days = 40/100 * 40/100
= 16/100 i.e 16%
probability that rain on any day = 1 -16/100 = 84/100 i.e 84%
