X ~ Uniform (a,b) = Uniform (2 , 12)
Where a = 2 , b = 12
P(x1 < X < x2) = (x2 - x1) / (b-a)
So,
P(4.30 < X < 8.70) = (8.70 - 4.30) / (12 - 2)
= 0.44

QUESTION 4 Suppose Xis a random variable with probability density function f(x) and Y is a random variable with density function f,(x). Then X and Y are called independent random variables if their joint density function is the product of their individual density functions: x, y We modelled waiting times by using exponential density functions if t <0 where μ is the average waiting time. In the next example we consider a situation with two independent waiting times. The joint...
