Virty [35]

Answer:

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 = $(1-P)^{100}$

probability of 1st defective = $(0.9983)^{100}$

probability of 1st defective = 0.844

so correct option is d. 0.844
