Or
How many probable numbers may show up in a single throw of an unbiased dice?
Or
How many possible outcomes are there of a single draw of a card of “Ace” from a pack of cards?
Or
In how many ways can one put 6 letters in 3 letter boxes?

Yes, a coin can have either a Heads or a Tail, hence, 2 ways.

A dice can throw up any number from 1 to 6 in one toss, hence, 6 ways.
Another dice can do the same in another 6 ways.
