y = 30- 2 = 28
28/4=7
So 7 per side of the square. x would then be 27-7-7= 13 counting from the top
y would be 2+7+7=16
(13,16)
P(x<10) =0
Step-by-step explanation:
M =1/μ
M= 1/15 =0.066667
X- Exp (0.066667)
Where: X is the random variable for number of days
P (X<x) = 1 - e^-mx
P(X - x) = 1 - e^-0.06666 x10
P(x<10) = 0
