Your son, Jason, left his skateboard at the bottom of your basement stairs. While going downstairs, you stepped on the skateboard and broke your ankle. The resulting medical bill was $2,755. How much would your homeowner's insurance pay if you had a $1,000 per-person limit on no-fault medical payments coverage?

The discrete random variables x and y take integer values with joint probability distribution given by f (x,y) = a(y−x+1) 0 ≤ x ≤ y ≤ 2 or =0 otherwise, where a is a constant. 1 tabulate the distribution and show that a = 0.1.2 find the marginal distributions of x and y. 3 calculate cov(x,y).4 state, giving a reason, whether x and y are independent. 5 calculate e(y|x = 1).
