A new game is being introduced at the Hard Rock Cafe. A ball is spun around a wheel until it comes to rest in one of many spots.
andriy [413]

Answer:

$ 1.96

Step-by-step explanation:

Number of spots with outcome of $1 = 9

Number of spots with outcome of $2 = 18

Number of spots with outcome of $10 = 1

Total number of spots = 28

Probability that ball will land on $1 = \frac{9}{28}

Probability that ball will land on $2 = \frac{18}{28}

Probability that ball will land on $10 = \frac{1}{28}

The amount that player should expect to win on average in equal to expected value of the game. Expected value is calculated as the summation of product of probabilities with their respective outcomes.

i.e. for this case:

Expected Value will be:

(1 \times \frac{9}{28})+(2 \times \frac{18}{28})+(10 \times \frac{1}{28})\\\\ =1.96

This means, on average the player should expect to win $ 1.96

Stella [2.4K]

<u>Answer:</u>

The correct answer option is b = -a.

<u>Step-by-step explanation:</u>

We know that a number b is located the same distance from 0 as another number, a, but in the opposite direction.

So, The equation will be b = -a which is the same as writing b = -1 * a.

Here, the negative sign with the 'a' will change it from positive to negative, or vice versa.

Recall how,

negative times positive is negative; and

negative times negative is positive.
