If I am dealt one card from a standard deck, what is the probability of me being dealt 3 of clubs?

The probability of an event occurring is equal to (a) the number of outcomes that satisfy the criteria for the event, divided by (b) the total number of possible outcomes. In this case the number of outcomes that satisfy the condition of 3 of clubs is one, because if you are dealt one card there is only one 3 of clubs in a deck. The total number of possible outcomes is 52, because you could be dealt any one of 52 cards. So the probability of being dealt a 3 of clubs is... can you finish it from here?
