Probability stats 1 help
A fair dice is thrown twice. If the second score is the same as the first, the second throw doesnt count and the dice is thrown again until a different score is obtained. The two different scores are added to give a total.
List the possible outcomes and find the probability that :
a. the total is 7
b.the total is at least 8
c.at least one of the two scores is a 6
d.the first score is higher than the last.

1/6 chance for each of the of the numbers on the first roll; 1/5 on the second (first number not allowed again). Make a list of all the possible outcomes (should be 30) and you should be able to able to find the probabilities asked.
