Answer:
probability (at least one defect is) is 0.096517 or 9.65 %
Explanation:
Given data
defect rate = 1%
no of sample = 10
to find out
probability at least one will have a defect
solution
we know here probability of defect is
Probability (defect) = 0.01
and n is 10
so
probability (at least one defect is) = 1 - probability (none) .............1
we know probability (none) = 0.99^n
probability (none) = 0.99^10
put this in equation 1
probability (at least one defect is) = 1 - 0.99^10
probability (at least one defect is) is 0.096517 or 9.65 %
