Question

9. A computer chip manufacturer knows that 72% of the chips produced are defective.

Answer 1

The probability that exactly 800 chips are acceptable is less than 0.000001

How to determine the probability?

The given parameters are:

• Sample, n = 3000
• Percentage acceptable, p = 72%
• Acceptable chips, x = 800

The binomial probability is represented as:

$P(x) = ^nC_x * p^x * (1- p)^{n - x}$

So, we have:

$P(300) = ^{3000}C_{800} * (72\%)^{800} * (1- 72\%)^{3000 - 800}$

The data values are large.

So, we use a statistical calculator to evaluate the expression

Using the calculator, we have:

P(300) < 0.000001

Hence, the probability that exactly 800 chips are acceptable is very small i.e. less than 0.000001
