for questions 8, 9, 10 and 11. I would like to see probability inequality, formula, and how you would approach to solving the problem please!

8.A hockey goaltender has a save percentage of 0.920. This means that the probability of any single shot taken on the goaltender being a goal is 0.08. What would be the expected number of goals scored on this goaltender in a game where she faced 35 shots?

9.A fair die has four faces numbered one to four. What is the probability of rolling a two exactly three times in ten rolls of the die?

10.A student writes a five question multiple-choice quiz. Each question has four possible responses. The student guesses at random for each question. Calculate the probability for each possible score on the test from 0 to 5.

11.A salesman has a 20% probability of making a sale to any customer who enters his department. On a typical day, he will meet 30 customers. What minimum number of sales will he have an 88% certainty of making for any given day?
