A lottery consists of one $2000 winner, three $500 winners, and ten $100 winners. a total of 1000 tickets are sold for $10 each.
Semenov [28]

Answer: -5.5

 

WOKINGS

Given that the lottery has the following number of winners:

One $2000 winner

Three $500 winners

Ten $100 winners

 

Also Given,

A total of 1000 tickets are sold

Each ticket costs $10

 

The expected winning for a person purchasing one ticket is the sum of the products of the gain/loss and their corresponding probability.

 

There is one $2000 winner

There are 1000 tickets

The probability of winning $2000

= 1/1000

= .001

There are three $500 winners

There are 1000 tickets

The probability of winning $500

= 3/1000

= .003

 


There are ten $100 winners

There are 1000 tickets

The probability of winning $100

= 10/1000

= .01

 

Since each ticket costs $10

Everyone who buys a ticket automatically loses $10.

Therefore, the probability of losing $10 is 1

 

Now to calculate the expected winning for a person purchasing one ticket

= 2000(.001) + 500(.003) + 100(.01) – 10(1)

= 2 + 1.5 + 1 – 10

= -5.5

 

The expected winning is -5.5. This implies that a person playing this lottery can expect to lose $5.50 for every one ticket that they purchase.

Cristy has ten pets including cats, birds, and hamsters. She has twice as many hamsters as cats.
marysya [2.9K]
6 hamsters, 3 cats, and 1 bird = 38 legs.

6H + 3C + 1B = 30

H = 4 C = 4 B = 2

6*4 + 3*4 + 1*2 = 38

Hope this helped :)

You toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one tail
forsale [732]
Seeing as there are three coins, which means there are 3 heads and 3 tails.There's only a 50% chance it'll land on either side one one coin. I believe the chances to get two heads, and one tail would be somewhere around 80%, since there are only 8 possible outcomes.
