Answer:

Explanation:

Hi there!

2Pb (no₃) -------> 2Pb + 4no₂ + o₂

Molecular mass of 4no₂ = 184g

Molecular mass of o₂ = 32g

From the reaction;

When 184 g of no₂  was formed 32 g of oxygen was formed.

When 1 g of no₂  was formed 32/184 g of oxygen was formed.

When 11.5 g of no₂  was formed (32/184)*11.5 g of oxygen was formed.

Therefore, when 11.5 g of no₂  was formed 2 g of oxygen was formed.

Hope it helps!

Complete Question:

a) List the values that y may take on and construct the pdf table

b) Calculate the average expected matches over the long run of playing this game for the player

c) Calculate the average expected earnings over the long run of playing this game for the player

Answer:

a) Y = { -1, 1, 2,3}

E(X) = 0.5

c) There is a loss of $0.0802

Explanation:

a) Y will take on the values, Y = { -1, 1, 2,3}

The pdf table is attached as a file to this solution

b) E(X) = 0.5

c)

The average expected matches, E(X) = np

where p = 1/6, n =3

E(X) = 3 * 1/6

E(X) = 0.5

c) Average expected earnings = \sum y P(Y)

P(y) can be seen from the pdf table in the file attached

Average expected earning = (-1*0.579) + (1*0.347) + (2*0.069) + (3 * 0.0046)

Average expected earning = -0.0802

This shows that instead of earning, there is a loss of $0.0802
