**Motivating the Binomial Distribution**

Recall last class we were introduced to the Frozen Dye Snow Cone
company.

They sell
snow cones to people at local fairs and sporting events according

to
the following probabilities for their four flavors.

Cherry 0.4

Grape 0.2

Blueberry 0.1

Orange 0.3

You may assume that customers choose flavors independently.

In-Class Activities:

1. What is the probability that of the next two customers, both
request grape?

2. What is the probability that of the next two customers,
exactly one requests grape?

3. What is the probability that of the next three customers, only
one requests grape?

4. What is the probability that of the next three customers,
exactly two request grape?

Now it gets tougher ...

5. What is the probability that of the next 6 customers, exactly
one wants grape?

6. What is the probability that of the next 6 customers, exactly
two want grape?

7. What is the probability that of the next 6 customers, exactly **x** want grape?
