An instant lottery game gives you probability 0.10 of winning on any one play. Plays are independent of each other. You play 4 times. a) If X is the number of times you win, contract the probability distribution of X. b) What is the probability that you don't win at all? c) What is the probability that you win at least once? d) What is the expected value of X? What is the standard deviation of X?
Problem: A game gives you the probability .10 of winning on any 1 play. Plays are independent of each other. You play a total of 4 times. Let X represent the number of times you win. a) What is the probability that you don't win at all? b) what is the probability that you win at least once? c) what is the probability that you win once or twice? d) what is the expected value of X? What is the...
In an instant lottery, your chances of winning are 0.2. If you play the lottery one time and outcomes are independent, the probability that you do NOT win is:
In an instant lottery, your chances of winning are 0.2. If you play the lottery eight times and outcomes are independent, find the probability that you win at most once. Show complete work
Your probability of winning a game of chance is 0.4. If you play the game 3 times, what is the probability that you will win exactly 2 times?
In a certain game of chance, your chances of winning are 0.2 on each play. If you play the game five times and outcomes of each play are independent, the probability that you win at least once is (A) 0.6723 (B) 0.1091 (C) 0.2000 (D) 0.3277 the answer is A but how is it A
Consider a chess tournament in which you play one game with each of 3 opponents, but you get to choose the order in which you play your opponents, knowing the probability of a win against each. You win the tournament if you win two games in a row, and you want to maximize the probability of winning. Assume that it is optimal to play the weakest opponent second, and that the order of playing the other two opponents doesn't matter....
It costs $6.25 to play a very simple game, in which a dealer gives you one card from a deck of 52 cards. If the card is a heart, spade, or diamond, you lose. If the card is a club other than the queen of clubs, you win $10.00. If the card is the queen of clubs, you win $48.50. The random variable x represents your net gain from playing this game once, or your winnings minus the cost to...
Let X denote the number of times you have to play a game in order to win once. Assume attempts are independent, and that the chance of winning each time you play is p. (a) Find the probability that X is even (as a function of p). [Hint: You’ll use a geometric series from calculus.] (b) What happens to your answer to (a) as p → 1?
X and Y play a series of games. X has a probability p of winning each game. To win the game, the player has to win 2 more games than the other first. (a) Find the probability that X is the overall winner. (b) Find the expected number of games played.
