The probability that a part produced by a certain? factory's assembly line will be defective is 0.035. find the probabilities that in a run of 44 ? items, the following results are obtained. ? (a) exactly 3 defective items ? (b) no defective items ? (c) at least 1 defective item

Step-by-step explanation:

P\left ( defective item\right )=0.035

Using binomial distribution

Where p= probability of success

q=probability of failure

Here p=0.035

q=1-0.035=0.965

(i)for exactly 3 defective items i.e. r=3

P=

P=

P=0.1317

(ii)No defective item i.e. r=0

P=

P=

P=0.2085

(iii)At least 1 defective item

P=1-P(zero defective item)

P=1-

P=1-

P=0.6671
