Suppose the 2 balls are chosen without replacement from an urn consisting of 5 white and 8 red balls. let xi equal 1 if the ith ball selected is white, and let it equal 0 otherwise. give the joint probability mass function of x1 and x2
a. x1 x2
b. x1 x2 x3

practice. practice. practice.

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
