There are 36 cards in a box with three different colors-6 yellow, 12 blue, 18 red. What is the probability of obtaining two yellow cards when randomly drawing two cards?
1/42= 0.02381
|
5/216 = 0.02315
|
1/35 = 0.02857
|
4/35 = 0.11429
|
9/35 = 0.25714

Yanıt Açıklaması:
This is how we formulate the probability: P(A1? A2 ) = P(A2|A1 )P(A1 ) = P(A1 )P(A2|A1 )
This is how we calculate the probability of drawing two yellow cards: 6/36.5/35=1/42= 0.02381
