kropot72 · Answer

A variable which has a binomial distribution has the following properties:
1) There is a fixed number of trials (individual repetitions)
2) Each trial is independent of the others.
3) Each trial has a constant probability of success.
4) There are only two possible outcomes, usually referred to as 'success' and 'failure'.

You need to assess each part of the question to see whether or not all the above properties apply.

1. 
1) There is a fixed number of trials. n = 10
2) The result of each trial has no effect on the result of any other trial. Each trial is independent of the others.
3) There are 13 cards in the suit of clubs in each pack of 52 cards. Therefore the probability of success (obtaining clubs) in each trial is p = 13/52
4) There are only two outcomes of each trial, clubs or not clubs.
