Answer: 14 tickets weren't sold.

Step-by-step explanation:

14 times 15 = 210

So there are 210 seats in the cinema.

The total is $1274 so you would divide

$6.50\sqrt{1274 \\$ which equals 196

Your final step is to subtract

210 (the total seats) minis 196 (seats sold) equals 14 seats not sold

Answer:

b) Binomial

c) Poisson

Step-by-step explanation:

The geometric distribution is the number of trials required to have r successes. The measures the number of sucesses(wins), not the number of trials required to win r games. So the geometric distribution does not apply.

For each match, there are only two possible outcomes, either the skilled player wins, or he does not. The probability of the skilled player winning a game is independent of other games. So the binomial distribution applies.

We can also find the expected number of wins of the skilled player, which is 15*0.9 = 13.5. The Poisson distribution is a discrete distribution in which the only parameter is the expected number of sucesses. So the Poisson distribution applies.

So the correct answer is:

b) Binomial

c) Poisson
