Answer:

The expectation is -$0.2632

Step-by-step explanation:

Consider the provided information.

The total number of balls are: 18 red + 18 black + 2 green = 38

If the ball lands on a red number, the player wins the amount of his bet.

The bat is ball will land on a red number.

The favorable outcomes are 18/38 and unfavorable are 20/38.

Let S be possible numerical outcomes of an experiment and P(S) be the probability.

The expectation can be calculated as:

E(x) = sum of S × P(S)

For S_1 = 5

P(S_1) = \frac{18}{38}

For S_2 = -5(negative sign represents the loss)

P(S_2) = \frac{20}{38}

Now, use the above formula.

E(x) = 5\times \frac{18}{38}-5\times \frac{20}{38}

E(x) = \frac{90}{38}-\frac{100}{38}

E(x) = \frac{-10}{38}

E(x) = -0.2632

Hence, the expectation is -$0.2632

Calculate the unpaid balance, finance charge, and new balance using the unpaid balance method.
Rufina [12.5K]

Answer:

Step-by-step explanation:

Previous balance = $410.22

Payments/credits = $160.00

unpaid balance : $410.22-$160.00=$250.22

Monthly rate = 1.25%

Finance charge : 1.25 % of $250.22=$3.7533

Total balance to be paid when Finance charge is included : $250.22+$3.7533=$253.9733

New balance :

$253.9733+$95.25=349.2233
