Answer:
3/29
Step-by-step explanation:
There are a total of 10+6+9+5 cards = 30
10 yellow, 6 green, 9 orange, and 5 red cards
Draw a card
P(yellow) = number of yellow cards/ total
=10/30 = 1/3
Now keep the yellow card
There are a total of 19+6+9+5 cards = 29
Draw a card
P(yellow) = number of yellow cards/ total
=9/29
P(yellow, not replaced, yellow) = 1/3 *9/29
=9 /87 =3/29
