Question 1059276: A pair of dice are tossed twice.
Find the probability that the first roll is a total of at least 8 and the second roll is a total of at least 5.
I know that:
#of favorable outcomes/total # of possible outcomes
I know that at least 8 would be 5/36
I know that at least 5 would be 4/36

The answer you gave was for exactly 8 and exactly 5 but the problem says at least 8 and at least 5.
At least means 8 or more and 5 or more.
So look at the total from 8 to 12 for the first one and from 5 to 12 for the second one.
At least 8 or 8-12:5%2B4%2B3%2B2%2B1=15
P=15%2F36=5%2F12

At least 5 or 5-12:4%2B5%2B6%2B5%2B4%2B3%2B2%2B1=30
P=30%2F36=5%2F6
