This is a hypergeometric problem. Np = 200 n = 100 r = 88+ p = .8 — Appeals Court Justice Ralph Adam Whine concerned that plea bargains are permitted

Appeals Court Justice Ralph Adam Whine is concerned that plea bargains are permitted in too many criminal cases. He suspects that the local District Attorney, Susan Blessner, is accepting more plea bargains just to jerk his chain. Whine knows that 80 percent of all cases in the entire state result in a plea bargain. DA Blessner handled 200 cases this month. Whine takes a sample of 100 cases and finds plea bargains in 88. What can you tell Justice Whine about this?
