Suppose that 3 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 (a) x1,x2; (b) x1,x2,x3.

i would say the third one.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .
