Answer:

0.8%  is a probability that a calculator chosen at random will be defective

Step-by-step explanation:

Probability of any event is given by:

P(A) = \frac{\text{Number of required outcomes}}{\text{Total number of possible outcomes}} where, A is any event.

As per the statement:

In a batch of 960 calculators, 8 were found to be defective.

here,

A = Defective calculator.

⇒Number of defective calculator = 8

and

Total number of outcomes = 960 calculators.

then by definition we have;

P(A) = \frac{8}{960}

Simplify:

P(A) \approx 0.00833333333 = 0.833333333 %

Therefore, a probability that a calculator chosen at random will be defective to the nearest tenth place is, 0.8 %
