Final answer:

This question is about calculating probabilities in a Mathematics context, focusing on drawing cards from a shuffled set in various scenarios and whether the draws are with or without replacement.

Step-by-step explanation:

To calculate the probability of specific outcomes when drawing two cards without replacement from a deck containing 5 green cards and 5 yellow cards, let's consider different scenarios:

Probability of drawing two green cards:

There are 5 green cards in the deck and 10 total cards. When drawing the first card, the probability of selecting a green card is 5/10. After selecting one green card, there are 4 green cards left out of 9 remaining cards. Therefore, the probability of drawing another green card on the second draw, given that the first was green, is 4/9.

To find the combined probability of both events occurring (drawing two green cards), you multiply the individual probabilities:

Probability = (5/10) * (4/9) = 20/90 = 2/9

Probability of drawing two yellow cards:

Similarly, there are 5 yellow cards in the deck. The probability of drawing a yellow card on the first draw is 5/10. After drawing one yellow card, there will be 4 yellow cards left out of 9 remaining cards. Therefore, the probability of drawing another yellow card, given that the first was yellow, is 4/9.

Combining both probabilities:

Probability = (5/10) * (4/9) = 20/90 = 2/9

Probability of drawing one green card and one yellow card:

This scenario involves two different outcomes: a green card followed by a yellow card, or a yellow card followed by a green card. We calculate both probabilities and add them together.

Probability of green then yellow = (5/10) * (5/9) = 25/90

Probability of yellow then green = (5/10) * (5/9) = 25/90

Combined probability = Probability of green then yellow + Probability of yellow then green

= 25/90 + 25/90

= 50/90

= 5/9

Therefore, the probabilities for the specific outcomes are:

Drawing two green cards: 2/9

Drawing two yellow cards: 2/9

Drawing one green card and one yellow card: 5/9
