Question

There are 45 candies in a bowl, 20 red and 25 yellow. If two are taken from the bowl, what is the probability they will be two red candies?

here is what I have but I need help with the rest or even knowing if I am right.

20/45

25/43

25 * 20 = 500

45 * 43 = 1935

0.25839 is decimal

Answer 1

label your results, such as

prob(red) = 20/45 = 4/9
prob(yellow) = 5/9

(don't just write down some arithmetic calculations,
e.g. what is 25*20 = 500 supposed to represent )

here is all you need

Prob(2 reds) = (20/45)(19/44) = 19/99

explanation:
prob(first red) = 20/45
there are now 19 reds left of the remaining 44 candies
so prob(another red) = 19/44
