<PRE><B>Question 163262</B>
The probability
that a given alternator will fail on a 1-hour flight is .02. What is the probability that (a) both will
fail? (b) Neither will fail? (c) One or the other will fail? Show all steps carefully.
-----------
Prob(both fail) = 0.02^2 = 0.0004
----------
Prob(neither fails) = 0.98^2 = 0.9604...
----------------
Prob(one or other fails) = 1 - [0.0004+0.9604] = 0.0392..
-----------------------------------
