Sarah’s work days from last year were selected at random and her work hours for each were recorded. The hours she worked were 7, 8, 9.5, 6.5, 10, 8, 7.5 and 9. If she worked 180 days last year, on how many of those days would you expect that she worked more than 7 hours?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
