Problem 8. Suppose that XGeom(p) and Y ~ Geom(r) are independent. Find the probability P(X <Y).
I got this one wrong. please help!

29. Let Z be a standard normal random variable. (a) Compute the probability F(a) = P(2? < a) in terms of the distribution function of Z. (b) Differentiating in a, show that Z2 has Gamma distribution with parameters α and θ = 2.
If X and Y have a joint probability density function specified by 2-(+2y) find P(X <Y).
Sketch and label, and estimate the z-score(s). Then use StatCrunch. a) That corresponds to a left tail area of 0.05 b) That separate the middle 90% of the area from area in the tails
Please help
