Need some help with getting aggregate unique customers by customer type values

[Slides]

Here's what my table looks like:
MyTable

Unique_ID[FONT=&quot][/FONT]​

Transaction_Type
[FONT=&quot][/FONT]​

Customer_ID[FONT=&quot][/FONT]​

1[FONT=&quot][/FONT]​

TypeA
[FONT=&quot][/FONT]
1

2[FONT=&quot][/FONT]​

TypeB 1

3[FONT=&quot][/FONT]​

TypeC
[FONT=&quot][/FONT]
2

4[FONT=&quot][/FONT]​

TypeD [FONT=&quot][/FONT]
3

Each row represents a transaction of some type. Each Customer_ID can be associated with multiple Transaction_Types. There are a set number of Transaction_Types (10).

How do I query the data to find out how many number of Transaction_Types unique customers had?

For example, the output would be:
Unique Customers Number of Transaction_Types 30,000 10 20,000 9 10,000 8 5,000 7 4,000 6 3,000 5 2,000 4 1,000 3 500 2 100 1
Beyond this, what would be the best way to find out which transaction types did customers have?

Unique Customers Number of TypeA Transaction_Types 30,000 10 20,000 9 10,000 8 5,000 7 4,000 6 3,000 5 2,000 4 1,000 3 500 2 100 1
Unique Customers Number of TypeB Transaction_Types 30,000 10 20,000 9 10,000 8 5,000 7 4,000 6 3,000 5 2,000 4 1,000 3 500 2 100 1

Is there a better way to show this information?

Thanks
