Question

What is the probability of randomly selecting one 9 from a standard deck of 52 cards

Answer 1

How many 9's are in the deck?

Answer 2

Like 4

Answer 3

So, what do you have?

Answer 4

if you want 1 card and there are 52 cards
you have 1/52 chance of getting that card correct?

so if you want a 9, but there are 4 of them, and you only want 1.... what do you get?

Answer 5

1/52

Answer 6

Or 1/39

Answer 7

you want 1 card out of 52 but there are 4 of the same card, so you have 4 times the chance of getting that card,
so you get 4 x 1/52

simplify

Answer 8

1/13
