There are n people eligible to vote in a certain election. voting requires registration. decisions are made independently. each of the n people will register with probability p 1 . given that a person registers, he or she will vote with probability p 2 . given that a person votes, he or she will vote for kodos (who is one of the candidates 1 ) with probability p 3 . what is the distribution of the number of votes for kodos (give the pmf, fully simplified, or the name of the distribution, including its parameters)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i think the correct option is the second option.

the answer is $42.96

step-by-step explanation:

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
