Question :
20% of memory chips made in certain plant are defective. Find the probability that in a lot of 100 randomly chosen for inspection.
i) atmost 15 will be defective
ii) exactly 15 will be defective
Obtain these probability also by using Normal Approximation to binomial probabilities.
ii) exactly 15 are defective
p(15,100,0.20) = = 0.005
i) at most 15 are defective ................Question 1
how should i do this ...........
P(x 15,100,0.20) = ........Is this correct ...........
Question 2)
And fr Normal Approximation should i use the following formula below
z =
