3. A pair of fair dice is tossed and the up face values are observed. Define X to be the number of twos observed. Find P(X = 0). Round your answer to the nearest thousandths. Answer =4. A pair of fair dice is tossed and the up face values are observed. Define X to be the number of ones observed. Find the mean of X. Round your answer to the nearest thousandths. Answer =5. Suppose X is a discrete random variable with possible values: X = 0, 1, or 2 Suppose P(X = 0) = 0.10, P(X = 1) = 0.30, and P(X = 2) = 0.60. Find the mean of X. Answer =6. Suppose X is a discrete random variable with possible values: X = 0, 1, or 2 Suppose P(X = 0) = 0.10, P(X = 1) = 0.30, and P(X = 2) = 0.60. Find the variance of X. Answer =7. Suppose X is a discrete random variable with variance 0.80. What is the standard deviation of X? Round your answer to the nearest thousandths. Answer =1. Suppose X is a binomial random variable with 6 trials and success probability 0.30. Find P(X = 2). Round your answer to the nearest hundredths. Answer =2. Suppose X is a binomial random variable with 4 trials and success probability 0.40. Find P(X 3). Round your answer to the nearest hundredths. Answer =4. Suppose X is a binomial random variable with 5 trials and success probability 0.40. Find the mean of X. Answer =5. Suppose X is a binomial random variable with 5 trials and success probability 0.30. Find the variance of X. Do not round your answer. Answer =6. Suppose X is a binomial random variable with 5 trials and success probability 0.40. What is the standard deviation of X? Round your answer to the nearest thousandths. Answer =
