Answer:

10,000 I think.

Step-by-step explanation:

10 x 1000. Put the 0 at the back. So it has 4 zero and so you put the zero at the back and what is 1 x 1 well it's 1, so it's 10,000. I think.

An urn contains 11 balls, 3 white, 3 red, and 5 blue balls. Take out two balls at random, without replacement. You win $1 for each red ball you select and lose a $1 for each white ball you select. Let X be the random variable that notes the amount you win. Find the probability mass function (p.m.f.) of X.

Answers

Answer with explanation:

Given: An urn contains 11 balls, 3 white, 3 red, and 5 blue balls.

You win $1 for each red ball you select and lose a $1 for each white ball you select.

Let X be the number of times you win.

The total number of ways to select 2 balls (order does not matter) =

The number of ways so that two balls are white (and X=-2):^3C_2=3

P(X=-2)=(3)/(55)

The number of ways so that two balls are red (and X=2):^3C_2=3

P(X=2)=(3)/(55)

The number of ways so that one ball is red, one is white (and X=0):^3C_1*^3C_1=9

The number of ways so that two balls are blue (and X=0 ): ^5C_2=(5 \cdot 4) / 2=10

i.e. P(X=0)=(10+9)/(55)=(19)/(55)

The number of ways so that one ball is blue, one is white (and X=-1 ): ^5C_1*^3C_1=15

P(X=-1)=(15)/(55) =(3)/(11)

The number of ways so that one ball is blue, one is red (and X=1 ): ^5C_1*^3C_1=15

P(X=1)=(15)/(55) =(3)/(11)

Thus, the probability mass function (p.m.f.) of X would be ( in attachment) :
