Question

What are is the probability of picking a number less than 4 from a deck of cards?

Answer 1

`3/13`

Explanation:

Assuming aces are lower than 4 then you have Ace, 2 and 3 each of which are repeated 4 times (as there are 4 different suits). So you have a total of `3times4=12` cards that you can pick which are less than 4. A deck has has 52 cards so the probability of randomly drawing a card less than 4 will be:

`P=12/52 = 3/13`

i.e. a 3 in 13 chance.
