Labtech is a company that manufactures microscopes and other laboratory instruments. on (ipoint) occasion, one of the microscopes is defective when it comes off of the production line. the probability that a microscope is defective is 0.17% find the probability that the first defective microscope comes after the first 100 microscopes off of the production line.

a. 0.156
b. 0.181
c. 0.742
d. 0.844

probability of 1st defective = 0.844

correct option is d. 0.844

Step-by-step explanation:

given data

probability defective = 0.17%

undefective microscopes = 100

to find out

the probability that the first defective microscope

solution

we know defective probability P = 0.17% = 0.0017

so non defective probability (1-P)   = 1 - 0.0017

non defective probability (1-P)  = 0.9983

and

1st defective come after 100 it mean 1st 100 are non defective so

probability of 1st defective =

probability of 1st defective =

probability of 1st defective = 0.844

so correct option is d. 0.844
