Example 8-17
Let the number of trials on which the first defective item occurs be denoted
by the random variable
X
. Then
X
is a geometric random variable with
= 6, and
= 0.01 (1%). Substituting into the formula, gives
That is, the probability of observing the first defective in this geometric
experiment is 0.0095, correct to four decimal places
.
