A slot machine at a casino randomly awards 20% of the attempts. Assume all attempts are independent. Let X be the number of attempts to get 3 awards. Which of the following distribution does X follow? O Binomial Distribution O Bernoulli Distribution O Hypergeometric Distribution O Negative Binomial Distribution Based on 12(a), find the distribution parameter(s): (type the parameter with letters and separate multiple parameter by comma, e.g. : n-3, p0.2) Based on 12(a), find the probability that the 3rd reward is obtained at the 10th attempt, ie., P(X-3). (Round to three decimals.)
