Dan has the option of taking one class or two classes per week.
If Dan takes one class per week then he can give training out of any three course...i.e 3C1 . Total possibilibiliy = 3.
If Dan takes two classes per week then he can give training out of three three course on first class ...i.e 3c1 = 3 - First class
he can give training out of three three course on second class ...i.e 3c1 = 3 - Second class..
When we add this we get total 9 possibilities...
IMO option D is correct answer...
OA please...will correct if I missed anything..

ALWAYS check the answer choices before starting any calculations.
Here the answer choices are all quite small, so we might just consider listing and counting all of the possible outcomes.
Let A, B and C represent the nights of the week when classes are offered.
Let Y, W and K represent yoga, weight training, and kickboxing
Now consider the possible outcomes if Dan decides to go to one class per week.
We get the following:
AY
AW
AK
BY
BW
BK
CY
CW
CK
TOTAL = 9 possibilities
Of course, that's just considering one class per week.
If we add a second class, there will be MORE THAN 9 possibilities.
