Two cards are drawn randomly without replacement from an ordinary deck. Let X be the number of hearts and Y be the number of black cards obtained. (a) Write an expression for the joint PMF f(x; y)
(b) Tabulate the joint PMF
(c) Find the marginal PMF of X and Y
(d) Find P(Y = 1jX = 1)
(e) Tabulate P(X + Y <= z) for all possible values of z

step-by-step explanation:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

slope is 35 and 20 miles is the y-intercept.
