1. Identify the parameterpin the following binomial distribution scenario. The probability of buying a movie ticket with a popcorn coupon is0.785, and the probability of buying a movie ticket without a popcorn coupon is0.215. If you buy18movie tickets, we want to know the probability that more than12of the tickets have popcorn coupons. (Consider tickets with popcorn coupons as successes in the binomial distribution.)
2. On average, Nancy has noticed that18trucks pass by her apartment daily (24hours). In order to find the probability that more than2trucks will pass her apartment in a3-hour time period using the Poisson distribution, find the average number of trucks per3hours. Round your answer to three decimal places, if necessary.
3. The total snowfall per year in Laytonville is normally distributed with mean99inches and standard deviation14inches. Based on the Empirical Rule, what is the probability that in a randomly selected year, the snowfall was less than127inches?Enter your answer as a percent rounded to2decimal places if necessary.

1.On average, Kris has noticed that19trains pass by his house daily (24hours) on the nearby train tracks. What is the probability that at most4trains will pass his house in a7-hour time period? (Round your answer to three decimal places.) Use poisson distribution:
