At a manufacturing plant where switches are made, it is a known fact that 2% of all switches are defective. If two switches are
olchik [2.2K]

Answer:

The probability that exactly one switch is good is

P(x) =0.0392

Step-by-step explanation:

The probability that a switch is defective is:

P(D) = \frac{2}{100} =0.02

The probability that a switch is not defective is

P(D') = 1-P(D)=0.98

Therefore, if two switches are selected, the probability that exactly 1 is good is:

P(1=1)=P (D) P (D ') + P (D') P (D)

P(x)=(0.02)(0.98) + (0.98)(0.02)

P(x) =0.0392
