Calculators function with multiple silicon chips, containing thousands of components.
Chips are mass-produced & have a relatively
high rate of failure. Suppose a calculator
uses two chips. Chip A has a 0.05 rate of
failure, and chip B has a 0.08 failure rate.
If one of each chip is selected at random,
what is each probability?
a. Both are defective.
b. Neither chip is defective.
c. At least one chip is defective.
