There are 10 yellow, 6 green, 9 orange, and 5 res cards in a stack of cards turned face down. once a card is selected, it is not replaced. determine each probability.

p(2 yellow cards)

10+6+9+5= 40

So there are

are yellow cards are green cards are orange cards red cards

now we have to get the percentages

=

=  

=  

=  

so the probability of getting...

yellow is 25%

green is 15%

orange is 22.5%

red is 12.5%
