Company x tested its light 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 $2,500 bulbs, there were 2200 bulbs that burnt out after more than 1500 hours of use. Lucy purchased a light bulb from company x. What is the likelihood that it will burn for more than 1500 hours? Please write the answer in decimal form
The likelihood that a light bulb purchased from company x will burn for more than 1500 hours is given by the number of bulbs that burnt out after more than 1500 hours divided by the total number of bulbs tested:
Likelihood = (2200/2500) = 0.88
Therefore, the likelihood that the light bulb will burn for more than 1500 hours is 0.88.
