. A hotel gives 10 free movie tickets to visitors every day. Historically 80% of free tickets are taken in any given day. a. What is the probability that 6 free tickets are taken by visitors in a random day?

b. If each visitor who has a free movie ticket, pays $10 to buy popcorn and pepsi, find the expected dollar amount that they spend on popcorn and pepsi.

c. If 40% of visitors who have free movie ticket dine-in in the hotel, find the probability that 6 free movie tickets are taken and four of those with free movie tickets dine-in in the hotel.

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general

i dont know

step-by-step explanation:

both equations and proportions are better.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
