Given that percent of computer infected which is found by quality control inspector = 1.3%
Total number of computers = 1500
Now we have to find the number of Defective computer. To find that we will just need to find the product of given defective percent by the total number of computers.
Total number of defective computers = 1.3% of 1500
Total number of defective computers = 0.013* 1500
Total number of defective computers = 19.5
Hence final answer is approx 20 computers.
