I would say take 2 from eight which equals 6
6x + 5x + (x + 16) + (3x - 1) = 360
11x + x + 16 + 3x - 1
15x + 15 = 360
15x = 345
x = 23
6(23) = 138
((23) + 16) = 39
(3(23) - 1) =68
5(23) = 115
138 + 39 + 68 + 115 = 360
3 and 3 1/5 because the median is always in the middle
Step-by-step explanation:
This event that's taking place is happening twice. The event is the mail getting delivered. It's happening two times. Luckily, you already know the probability of it happening once. Because it happens twice, you just square it. (0.9)^2. 0.81 chance of it happening in two consecutive days.
