The probability of winning the top prize on a Plinko board is 0.24. The game is played 50 times. Assume that the number of times a person can win is normally distributed. (binomial) a) What is the expected mean number of wins? (2 marks) b) What is the expected standard deviation of number of wins? (2 marks) c) What is the probability of winning exactly 15 times? (4 marks)
Added by James K.
Step 1
Given that the probability of winning is 0.24 and the game is played 50 times, we can find the expected mean number of wins by multiplying the number of games by the probability of winning. Mean = 50 * 0.24 = 12 Show more…

Dice and dollars You roll a die, winning nothing if the number of spots is odd, $1 for a 2 or a 4, and $10 for a 6. a) Find the expected value and standard deviation of your prospective winnings. b) You play twice. Find the mean and standard deviation of your total winnings. c) You play 40 times. What's the probability that you win at least $100?

From the Data at Hand to the World at Large
Sampling Distribution Models
You play two games against the same opponent. The probability you win the first game is 0.4. If you win the first game, the probability you also win the second is $0.2 .$ If you lose the first game, the probability that you win the second is 0.3 a) Are the two games independent? Explain. b) What's the probability you lose both games? c) What's the probability you win both games? d) Let random variable $X$ be the number of games you win. Find the probability model for $X .$ e) What are the expected value and standard deviation?
