Solution:-
b) The probability that this shipment is not accepted if 20% of the total shipment is defective is 0.763.
n = 19, p = 0.20
x = 2
By applying binomial distribution:-
P(x,n) = nCx*px*(1-p)(n-x)
P(x > 2) = 1 - [P(x = 0) + P(x = 1) + P(x = 2)]
P(x > 2) = 0.7631

A stationary store has decided to accept a large shipment of ball-point pens if an inspection of 15 randomly selected pens yields no more than two defective pens. (a) Find the probability that this shipment is accepted if 5% of the total shipment is defective. (Use 3 decimal places.) (b) Find the probability that this shipment is not accepted if 15% of the total shipment is defective. (Use 3 decimal places.)
A stationery store has found that 5% of ball-point pens are defective. The store will accept a large shipment if an inspection of 25 randomly selected pens contains no more than 2 defective pens. Find the probability that the shipment will be accepted. Probability = (round answer to three decimal places)
