Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. On a firing range, a rifleman has two attempts to hit a target. The probability of hitting the target with the first shot is 0.2 and the probability of hitting with the second shot is 0.3. The probability of hitting the target with both shots is 0.1.
Find the probability of
a missing the target with both shots, b hitting with the first shot and missing with the second.

I drew a venn diagram and correctly got 0.6 for the first question.

The second question, however, I got 0.14.
