How many hours will it take to assemble the Ferris wheel? You have - ProProfs Discuss

# How many hours will it take to assemble the Ferris wheel? You have run away and joined the carnival as a project manager and are in charge of constructing the Ferris wheel in each town the carnival visits. However, this is something you have never done before and you are getting different opinions from others on how long it takes. Joe is new and has given you what you believe to be an optimistic estimate of 3 hours, Bill says it will take 10 hours, which seems too long to you and quite pessimistic. Lastly, Margie, who is the most experienced at this task is telling you it will take 8 hours. You are not sure who to believe, so you decide to do a PERT estimation. A. 7 hoursB. 21 hoursC. 8 hoursD. 5 hours

In this question O = 3 , Most Likely = 8 and P = 10 , So, C= 3+84+10/6 Which will be 7.5 (which is not given) and system is showing 5 as correct.

Correct response it is C.
(3+48+10)/6 ~=8
(optimistic + (most likely 4) + pessimistic)/6
