Problem 115E
Suppose that a radio contains six transistors, two of which are defective. Three transistors are selected at random, removed from the radio, and inspected. Let Y equal the number of defectives observed, where Y = 0, 1, or 2. Find the probability distribution for Y. Express your results graphically as a probability histogram.

Problem 115E
Suppose that a radio contains six transistors, two of which are defective. Three transistors are selected at random, removed from the radio, and inspected. Let Y equal the number of defectives observed, where Y = 0, 1, or 2. Find the probability distribution for Y. Express your results graphically as a probability histogram.
ANSWER:
Solution:
Step 1 of 3:
It is given that a radio contains six transistors in which two are defectives.
Three transistors are taken out from the radio at random and inspected. Let Y be the number of defectives observed and Y can take values 0,1,2.
We have to find the probability distribution of Y and also we have to obtain the probability histogram.
