how would I figure these out assuming I had the results of my simulation?

1. In Johnís class there are 22 students (including John) trying to collect the Native Bird card set.
Use the results of your simulation to estimate:
a) how many students will have 3 different cards in the set after collecting 4 cards
b) how many of the students could expect to have the set of 4 cards once they have collected less than or equal to 8 cards.
