Answer:
Step-by-step explanation:
Given that the proportion of murders with firearm is 79.2 %
Each murder is independent and there are two outcomes either with fire arm or without fire arm.
Hence X no of murders with fire arm is binomial with n = 200 and p = 0.792
q=1-0.792 = 0.208
a) Expected value of x = np

b) P(X=173) = 0.002289
Since probability is very low it can be concluded it would be unusual to observe 173 murders by firearm in a random sample of 200 murders
