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.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )
