A Washington scratch off lotto ticket will be a winner one out of five times. Out of a shipment of n = 190 Washington lotto tickets, find the probability for the lotto tickets that there are somewhere between 34 and 54 prizes. Hint: Normal Distribution distribution information

n = 190; p = 1/5 = 0.2; q = 0.8

μ = np = (190)(0.2) = 38

σ = npq = (190)(0.2)(0.8) = 5.51 (rounded off to nearest hundredths)
