Question

box contains 12 items of which 3 are defective. A sample of 3 items is selected from the box. Find the probability distribution of the number of defective items.

Answer 1

Total= 12
Probable= 3
Probability= 3/12
= 1/4
=0.25

Answer 2

Hiiiii....

here is ur answer.....

total number of items =12

defective items = 3

3items is selected....

to find the probability ofdistribution of defective items......

probability= number of favourable outcomes/ total possible outcomes....

p(defective pens) = 3/12
probability= 1/4 = 0.25.

Therefore the probability of defective items is 1/4 = 0.25..

hope it helps you mark it as brainliest......
