Suppose that you have 8 cards. 5 are green and 3 are yellow. The 5 green cards are numbered 1, 2, 3, 4, and 5. The 3 yellow cards are numbered 1, 2, and 3. The cards are well shuffled. You randomly draw one card. G = card drawn is green
E = card drawn is even-numbered

Suppose that this time you randomly draw two cards, one at a time, and without replacement.
G1= first card is green
G2= second card is green

1) What is the probability of G1 and G2?
G1: ⅝ G2: 4/7
2) What is the probability of at least one green? 25/28
3) What is the probability of P(G1 | G2)?

Can someone help me with number 3? I do not understand how to solve for it given that there is two unknowns. Thank you!
