In a batch of 890 calculators, 12 were found to be defective. what is the probability that a calculator chosen at random will be defective? write the probability as a percent. round to the nearest tenth of a percent if necessary.

a.74%

b.1.3%

c.98.7%

d.1.8%

1.3%

Step-by-step explanation:

Given: The number of calculators T= 890

The number of defective calculators D= 12

Now, the probability that a calculator chosen at random will be defective is given by :-

P(defective )

⇒P(defective )

In percent, P(defective )

Hence, the probability that a calculator chosen at random will be defective = 1.3%
