a. Explanation Given info: When playing roulette, the probability to get number 7 is 0.03. Calculation: Mean of Binomial distribution: The formula is, μ = n p Where, n is the number of trials and p is the probability of success for each trial and q is the probability of failure for each trial. Substitute n as 50 , p as 0.03 μ = ( 50 ) ( 0.026 ) = 1.32 Thus, the mean number of person getting tattoo at their young age is 74 adults . Standard deviation of Binomial distribution : σ = n p q Substitute n as 50 , p as 0 b. To determine To check: Whether 0 wins in 50 bets unusually low number of wins or not.
