Mary, Susan, and Sarah are running a beach boutique on the board walk of Ocean City. Their favorite product is a red lifeguard hoody. Mary believes it will sell 341 times next season. Susan forecasts sales of 535, and Sarah forecasts 199 What would be the result of a simple forecast combination? (Round to two decimal places)

358.33 times

Explanation:

The computation of the simple forecast combination is shown below:

= (Forecast sales done by Mary + Forecast sales done by Susan + Forecast sales done by Sarah) ÷ (Total number of observations)

= (341 + 535 + 199) ÷ (3)

= (1,075)  ÷ (3)

= 358.33 times

We simply divided the total sales forecasted done by each one by the total number of observations

there's 11 people for the 1st position. then, no matter who gets it, there's only 10 left for the second, and then 9 left for the third. 11 x 10 x 9 = 990.   the answer is there are 990 different ways the positions can be filled by these applicants
