According to a report, 51.6% of murders are committed with a firearm. (a) if 200 murders are randomly selected, how many would we expect to be committed with a firearm? (b) would it be unusual to observe 122 murders by firearm in a random sample of 200 murders? why?

b) As we have selected the people randomly, we have no control over the type of people we are given - this is theoretical and the estimate is not definite - all of the sample could have murdered by firearm or even none (even though it is highly unlikely).
