Anyway, the Alcatraz was an attempt to reclaim the Island for Alcatraz for Native Americans; and the basis for their claim to it was the treaty of 1868 in which all abandoned land was to be returned to the Native Americans (but Alcatraz wasn't).
Answer: The probability of getting a large particle of contaminant in a 125 wafers is 1e-250 = 1×10^-250.
Explanation: Probability is the possible chances of an event to occurs.
The probability of a wafer to contain a large particle of contaminant is;
0.01
Because the possibility of a wafers to contain a large particle of contaminant are independent to each other, therefore the probability of 125 wafers to contain large particle of contaminant will be;
0.01^125 = 1 × 10^-250 = 1e-250
This means that it will be very difficult to identify a large particle of contaminant in 125 wafers
