02. In a mass production of bolts, it is found that 5% are defective. Bolts are selected at random and put into packets of ten. A packet is selected is selected at random. Find the probability that it contains a) Three defective bolts P(X= 3). b) Less than three defective bolts P(X < 3). Two packets are selected at random. c) Find the probability that there are no defective bolts in either packet P(X = 0).
