Question

Company X tested its light bulbs to see how long they would last. On a production line, 2,500 bulbs were taken and tested. The department in charge reported that out of 2,500 bulbs, there were 2,200 bulbs that burnt out after more than 1,500 hours of use. Lucy purchased a light bulb from Company X. What is the likelihood that it will burn for more than 1,500 hours? Write your answer in decimal form.(1 poin

Answer 1

To calculate the likelihood that Lucy's light bulb will burn for more than 1,500 hours, we can use the ratio of bulbs that burnt out after more than 1,500 hours to the total number of bulbs tested.

Likelihood = number of bulbs burnt out after more than 1,500 hours / total number of bulbs tested
Likelihood = 2,200 / 2,500
Likelihood = 0.88

Therefore, the likelihood that Lucy's light bulb will burn for more than 1,500 hours is 0.88, or 88%.
