15. Chips. A computer chip manufacturer rejects 2% of the chips produced because they fail to work properly when tested. Suppose the company tests 10 chips. What’s the probability of these results? a) All 10 are okay. (None of the chips fails the test.) (ie. 0.001)

b) Exactly 1 of the 10 chips fails. (ie. 0.001)

c) Exactly 2 of the 10 chips fail. (ie. 0.001)

d) Exactly 3 of the 10 chips fail. (ie. 0.0001)

e) No more than 3 of the 10 chips fail the test. (ie. 0.0001)
