The lottery is played all around the world. More than two-thirds of the citizens of the state. Anny three digit number can be placed from 000 to 999. After than the randomly draw a number. A number is drawn at random and announced by the state. The winner gets a prize. The probability that the correct 3 digits in the right order is selected is at an odds of 1 in 1,000. So if If a ticket costs two dollars and the winner must pick a sequence of five digits then if There are 10^5=100,000 different combinations of 5 digit numbers and only the right combination wins the probability to win is at a 1 in 100000 chance to win. The chance to lose the 2 dollars put in is at a probability of 99999 in 100000 chance. Even if you win the prize you would lose

The probability of its possible values from impossible to certain.
An example is like asking your father for some money. But as an alternative, instead of giving you money, he decides to have fun with it. He decides to flip a coin. It depend on what the coin lands on if you will receive money or not. If the coin lands on “heads” yo win and he will give you 20 dollars. If you are unlucky and the coin lands on tails, you lose, and will receive nothing.‘In this example, we would say that the payout associated with the event that the coin lands “heads” is $20, and the payout associated with “tails” is $0. ‘) but before saying yes and accepting your father 's offer you go and ask your mother for some extra money. She decides to play a game with you too just like your father.she makes a different offer. She will roll a die, and give you $3 for every spot that turns up. Her offer is , if she rolls a 1, she will give you $3; if she rolls a 2, she will give you $6.00 (= 2 x $3.00), ... if she rolls a 6, she will give you $18 (= 6 x $3.00)). You decided to see witch one is a better offer to take.“ the most common way of evaluating these alternatives is to calculate the …show more content…
We can use a variable, such as X to indicate the possible payouts. There are two possible outcomes, “heads” and “tails”. The payout you receive if the coin lands “heads” is $20, and we write: XH = $20. Similarly, if the coin lands “tails” you get nothing,“)
‘In this simple case, the expected value is given by the equation: E(X) = ( pH x XH ) + ( pT x XT ) ⇔ E(X) = ( x 20 ) + ( x 0 ) ⇔ E(X) = ( 10 ) + ( 0 ) ⇔ E(X) = $10.00 . after you evaluate your mother’s offer. You find out that the expected value here is: E(X) = ( p1 x X1 ) + ( p2 x X2 ) + ( p3 x X3 ) + ( p4 x X4 ) + ( p5 x X5 ) + ( p6 x X6 ) ⇔ E(X) = ( x X1 ) + ( x X2 ) + ( x X3 ) + ( x X4 ) + ( x X5 ) + ( x X6 ) ⇔ E(X) = ( x 3 ) + ( x 6 ) + ( x 9 ) + ( x 12 ) + ( x 15 ) + ( x 18 ) ⇔ E(X) = x (3 + 6 + 9 + 12 + 15 + 18 ) ⇔ E(X) = x (63) ⇔ E(X) = $10.50”
Once you are done comparing your parents offers you decide the probability of getting more money will happen if you take your mother 's offer, and not your father
