No more than one means one and less so find the probability of zero and 1 defect and add them.
P%280%29=C%2825%2C0%29%280.01%29%5E0%2A%280.99%29%5E%2825-0%29=1%2A1%2A0.778=0.778
P%281%29=C%2825%2C1%29%280.01%29%5E1%2A%280.99%29%5E%2825-1%29=25%2A0.01%2A0.786=0.196
P=P%280%29%2BP%281%29
P=0.778%2B0.196
P=0.974
