In a Group of 200 Items, If the Probability of Getting a Defective Item is 0.2, Write the Mean of the Distribution. - Mathematics

Short Note

In a group of 200 items, if the probability of getting a defective item is 0.2, write the mean of the distribution.

Solution

It is given that the binomial distribution's p =0.2 and number of items (n) = 200

Hence,$\text{ mean, i . e . } np = 200 (0 . 2) = 40$
