In a recent school election at a large school we know that 45% of the students supported candidate x and the other 55% supported candidate y. assume everyone has a strong opinion about one candidate or the other. if we select 2 students at random what is the probability that they both supported the same candidate?

0.5050

Step-by-step explanation:

Given that in a recent school election at a large school we know that 45% of the students supported candidate X and the other 55% supported candidate Y.

We know that each candidate is independent of other

Hence prob for supporting X = 0.45 for each student and y = 0.55

We select 2 students at random

The prob that they  both supported the same candidate

=Prob both supported X or prob both supported Y

=prob both supported X + prob both supported Y(since mutually exclusive)

=

it is part of the rising action that reveals public sentiment toward hester.

explanation:

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
