A bag contains 3 gold marbles, 6 silver marbles, and 30 black marbles. The rules of the game are as follows: You randomly select

GaryK [48]

Answer:

The expected profit is $0.23077.

Step-by-step explanation:

From the given information it is clear that

Gold marbles = 3

Silver marbles = 6

Black marbles = 30

Total number of marbles = 3+6+30=39

The probability of selecting gold marble is

$\frac{3}{39}=\frac{1}{13}$

The probability of selecting silver marble is

$\frac{6}{39}=\frac{2}{13}$

The probability of selecting black marble is

$\frac{30}{39}=\frac{10}{13}$

It is given that If it is gold, you win $6, if it is silver, you win $5. If it costs $1 to play. Then the expected profit is

Expected profit or loss = 6(Probability of gold marble)+5(Probability of silver marble)-1

Expected profit or loss = $6(\frac{1}{13})+5(\frac{2}{13})-1$

Expected profit or loss = $\frac{6}{13}+\frac{10}{13}-1$

Expected profit or loss = $\frac{6+10-13}{13}$

Expected profit or loss = $\frac{3}{13}$

Expected profit or loss = 0.23076923

Expected profit or loss ≈ 0.23077

Positive sigh represents the profit.

Therefore the expected profit is $0.23077.

What is the slope of a line that goes through the points (4, 2) and (3, 1)?

dedylja [7]

Answer:

Step-by-step explanation:

Slope = y2 - y1 /x2 - x1

x1 = 4

y1 = 2

x2 = 3

y2 = 1

Slope = 1 - 2 / 3 - 4

= -1/-1

= 1

zysi [14]

Answer:

0.7755

Step-by-step explanation:

If 120 CDs are defective, the number of non-defective CDs in the batch is:

$n=1950-120\\n=1830$

In order for the batch to be accepted, all of the 4 CDs in the sample must not be defective, the probability of that happening is:

$P=\frac{1830}{1950}*\frac{1829}{1949} *\frac{1828}{1948} *\frac{1827}{1947}\\P=0.7755$

The probability that the entire batch will be accepted is 0.7755.
