Determine the probabilities below a) P(x=2) b) P(xs1) c) P(x> 3) a) P(x. 2)- (Round to four decimal places as needed.) ox and then click Check Answer Enter your answer in the answer b MacBook Air

Explanation / Answer

p = 0.65 n = 5

a) P(x=2) = 5!/(2!)(3!) * (0.65)^2*(1-0.65)^3 = 0.18114    (Rounding off will give 0.1811)

b) P(x<=1) = P(x=0) + P(x=1)

            = 5!/(0)!5! * (0.65)^0*(1-0.65)^5 + 5!/(1)!4! * (0.65)^1*(1-0.65)^4
            = 0.0052 + 0.04877
             = 0.05397
c) P(x>3) = P(x=4) + P(x=5)
          = 5!/(1)!4! * (0.65)^4*(1-0.65)^1 + 5!/(0)!5! * (0.65)^5*(1-0.65)^0
          = 0.3123 + 0.1160
          = 0.4283
