Answer:

0.206

Step-by-step explanation:

Use binomial probability.

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

n = 15, r = 10, p = 0.7, and q = 0.3.

P = ₁₅C₁₀ 0.7¹⁰ 0.3⁵

P = 0.206

Many times business will raise the prices of their goods
hjlf

The price that will maximize profit is $ 5.50.

Since an auditorium has seats for 1200 people, and for the past several days, the auditorium has been filled to capacity for each show, and tickets currently cost $ 5.00 and the owner wants to increase the ticket prices, and he estimates that for each $ 0.50 increase in price, 100 fewer people will attend, to determine which is the price that will maximize profit, the following calculation must be made:

  • 1200 x 5 = 6000
  • 1100 x 5.5 = 6050
  • 1000 x 6 = 6000

Therefore, the price that will maximize profit is $ 5.50.
