Answer:
attached below
Step-by-step explanation:
Assuming that Y1 and Y2 are independent exponential random variable with mean 3
where : U = Y1 + Y2 applying the property of exponential distribution sum of exponentials will follow a gamma distribution
i.e. ∝ = 2 , and β = 1
note : U = 2X
Hence probability distribution function X =
Fx (x) = p( X ≤ x )
= p( U ≤ 2x )
= Fu (2x)
probability density function X
f (x) = = 2 Fu (2x)
attached below is the remaining part of the solution
We know angle x=y(vertically opposite angles)
Since 3 angles lie on a straight line,
y+60+70=180 (linear pair)
y+130=180
y=180-130
y=50 degrees
Answer:
75% chance not to be picked since 1/4 is 25% and 16 divided by 4 is 4 and 4 is a whole so if you take 1/4 of it out you get 3/4 and 3/4 is 75%. I hoped I helped you
