A certain casino game has a wheel with 5 different animals on it. It costs $10 to bet on an animal, and
Mrrafil [7]

Answer:

Expected value = - $ 4

Step-by-step explanation:

Number of animals on the wheel = 5

Number of animals the player can bet on = 1

The player will win if the ticker stops on the chosen animal. Since, only one animal can be chosen out of 5, the probability of winning will be = \frac{1}{5}

If the ticker stops on any of the rest 4 animals, the player will lose. So the probability of losing will be =  \frac{4}{5}

If the ticker stops on chosen animal, the winning amount is $ 20, if the ticker lands on any of other animal, its a loss of $ 10.

We need to calculate the expected value of this game. Expected value is calculated by multiplying the probability of each outcome with the outcome and then adding these products.

So, for this case, the expected value will be:

(Probability of winning x Outcome on winning) + (Probability of losing x Outcome of losing)

Using the values, we get:

E=\frac{1}{5}(20)+\frac{4}{5}(-10)=-4

Minus sign has been used with 10, because the money is being lost.

Thus, the expected value of the game is - $ 4. This means, on average a player who will play the game is expected to lose about $ 4 per game

What is the sum of the first 10 positive integers?<br><br> A) 55<br> B) 50 <br> C) 100<br> D) 95
olga2289 [7]
The correct answer here is A) 55. This is because a positive integer is defined as any number greater than 0 and has no decimals/ fractions in it. Therefore, you would add 1+2+3+4+5+6+7+8+9+10, yielding 55 as your answer.

A recent survey of
Serga [27]

Answer:

The total number of students in a survey is 300.

Let the number of junior male(JM) be x and the number of senior males(SM) be y.

Let the number of junior female(JF) be p and the number of senior males(SF) be q.

It is given that there are 160 males, 80 junior females, 130 seniors.

Since number of males are 160. So the number of females are,

300-160=140

Since number of junior females is 80.

JF+SF=140\\80+SF=140\\SF=60

Since number of seniors are 130.

SM+SF=130\\SM+60=130\\SM=70

Since number of males is 160.

JM+SM=160\\JM+70=160\\JM=90

Therefore, the table and venn diagram is shown below.
