Question

In proof testing of circuit boards, the probability that any particular diode will fail is 0.01. Suppose a circuit board contains 200 diodes.

(a) How many diodes would you expect to fail?
2 diodes

Answer 1

Answer: 2 diodes

Step-by-step explanation:

Given : In proof testing of circuit boards, the probability that any particular diode will fail is 0.01.

The number of diodes contained by circuit board = 200

Then , the expected number of diodes to fail is given by :-

`0.01*200=2`

Therefore, there are 2 diodes that we will expect to fail.
