Step-by-step explanation:
Given that:
Price of each comb = $
15 combs were purchased in = $
To find:
Amount of discount offered on each comb.
Solution:
First of all, let us calculate the price of 15 combs at the price of $ each.
Original Price of 15 combs = Price of one comb Number of combs = $15
Now, there is some discount provided on the purchase of 15 combs.

According to the Binomial probability distribution ,
Let x be the binomial variable .
Then the probability of getting success in x trials , is given by :
, where n is the total number of trials or the sample size and p is the probability of getting success in each trial.
As per given , we have
n = 15
Let x be the number of defective components.
Probability of getting defective components = P = 0.03
The whole batch can be accepted if there are at most two defective components. .
The probability that the whole lot is accepted :
∴The probability that the whole lot is accepted = 0.99063
For sample size n= 2500
Expected value :
The expected value = 75
Standard deviation :
The standard deviation = 8.53
