A game of chance involves rolling an unevenly balanced 4-sided die. The probability that a roll comes up 1 is 0.22, the probabil

Answer:

Expected Winnings = 2.6

Step-by-step explanation:

Since the probability of rolling a 1 is 0.22 and the probability of rolling either a 1 or a 2 is 0.42, the probability of rolling only a 2 can be determined as:

$P_{1,2} = P_{1}+P_{2}\\P_{2} = 0.42 - 0.22 = 0.20$

The same logic can be applied to find the probability of rolling a 3

$P_{2,3} = P_{2}+P_{3}\\P_{3} = 0.54 - 0.20 = 0.34$

The sum of all probabilities must equal 1.00, so the probability of rolling a 4 is:

$P_{4} =1- P_{1}+P_{2}+P_{3} = 1-0.22+0.20+0.34\\P_{4}=0.24$

The expected winnings (EW) is found by adding the product of each value by its likelihood:

$EW=1*P_{1}+2*P_{2}+ 3*P_{3}+ 4*P_{4} \\EW=1*0.22+2*0.20+ 3*0.34+ 4*0.24\\EW=2.6$

Expected Winnings = 2.6

Remove the parentheses from the expression (–2) – (–3). A. 2 – 3 B. –2 + 3 C. 2 + 3 D. –2 – 3

lukranit [14]

Answer:

Step-by-step explanation:

The negative of a negative is a positive, so B is your choice. Think of it anothe way, if it helps. Imagine that the expression is this:

(-2) + (-1)(-3) since every subtraction problem can be rewritten as an addition problem.

We would first, by orders of operation, multiply the -1 and the -3 getting 3. Then the problem would simplify down to -2 + 3

Just another idea to ponder...

Write as an algebraic expression

Mazyrski [523]

Answer:

13) x=n-11

15) x=3*10

Step-by-step explanation:

I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!
