This is a binomial distribution where 80% of flights arrive on time (p = 0.8) and 20% do not (q = 1 - 0.8 = 0.2). Then the probability that exactly 2 flights arrive late follows the formula:
(nCr)(p^r)(q^(n-r)), where n = 16 (total # of flights), r = 14 (flights that arrive on time)
(16C14)(0.8^14)(0.2^2) = 0.2111
You put 5.75 in the box all u have to do is subtract 49.65 by 43.9 to get your answer
Answer:
hi sry i dont get what to write for an expression cause i dont have a number but i can tell you what to do! to find out what 15% of something is divide the number by 100 and the number you get after dividing multipy by 15 and you have you answer then all you have to do is put it in a expression!
