A survey is taken among customers of a fast-food restaurant to determine preference for hamburger or chicken. Of 200 respondents
kicyunya [14]

Answer:

                          Hamburger       Chicken

Adults                    65                        60         125

children                 55                        20          75

                             120                        80         200

a)What is the probability that a randomly selected individual is an adult?

Total no. of adults = 125

Total no. of people  200

The probability that a randomly selected individual is an adult = \frac{125}{200}=0.625

b) What is the probability that a randomly selected individual is a child and prefers chicken?

No. of child prefers chicken = 20

The probability that a randomly selected individual is a child and prefers chicken= \frac{20}{200}=0.1

c)Given the person is a child, what is the probability that this child prefers a hamburger?

No. of children prefer hamburger = 55

No. of child = 75

The probability that this child prefers a hamburger= \frac{35}{75}=0.46

d) Assume we know that a person has ordered chicken, what is the probability that this individual is an adult?

No. of adults prefer chicken = 60

No. of total people like chicken = 80

A person has ordered chicken, the probability that this individual is an adult= \frac{60}{80}=0.75

kiruha [24]

Answer:

2184 different skateboards can Bruno create

================================================

Step-by-step explanation:

The skateboard store has 3 types of grip tape, 13 types of decks, 7 types of trucks, 4 types of bearings, and 2 types of wheels.

AS skateboard will contain only one type of each component.

So, the number of skateboards can Bruno create =

= 3 * 13 * 7 * 4 * 2 = 2184 skateboards.

we have used the Multiplication Rule to find the outcomes from 5 independent types.
