Two random variable are independent and each has a binomial distribution with success probability 0.3 and 2 trials.
a) Find the joint probablity distribution
b) Find the probablity that the second random variable is greater than the first.
How do you do this problem??? Please help. Thanks!!!
Construct a 3x3 grid to represent the pairs (x, y) where x = 0, 1, 2 and y = 0, 1, 2.Quote:

And you should know how to use the binomial distribution to calculate the probabilities of X = x and Y = y for x = 0, 1, 2 and y = 0, 1, 2.
