b) The probability density function fZ(z) of Z = XY is calculated in the attached picture.
c) Computing E(Z) gives 1/4
Step-by-step explanation:
Comparing the computation of E(Z) using the answer to b), it shows that the values are equal.
Answer:
19, 2
Step-by-step explanation:
let the 2 numbers be x and y with x > y , then
x + y = 21 → (1)
x - y = 17 → (2)
Add the 2 equations term by term to eliminate y , that is
2x = 38 ( divide both sides by 2 )
x = 19
substitute x = 19 into (1) for value of y
19 + y = 21 ( subtract 19 from both sides )
y = 2
The 2 numbers are 19 and 2
