The probability of rain is 40% on Friday, 60% on Saturday, and 10% on Sunday. What is the probability that it will not rain during this three-day time period? And how do you get it.

4/10 chance of rain Friday, 6/10 chance Saturday and 1/10 chance Sunday.

That means the chances of it not raining are 6/10 4/10 and 9/10

You multiply these together to get the chances of it not raining.

You get 216/1000 or. 216 or 2.16% chance of it not raining
