Question

Company Ex tested in slight bulbs to see how long they would last on a production line 2500 bulbs were taken and tested. The department in charge reported that out of 2500 bulbs there were two 2200 bulbs that burn out after more than 1500 hours of use Lucy purchased the lightbulb from company X what is the likelihood that it will burn for more than 1500 write your answer in decimal form.

Answer 1

The probability that a lightbulb from Company X will burn for more than 1500 hours can be calculated by finding the ratio of the number of bulbs that burned for more than 1500 hours to the total number of bulbs tested.

So, the probability is (2200/2500) = 0.88

Therefore, the likelihood that a lightbulb from Company X will burn for more than 1500 hours is 0.88 or 88%.
