7 twice in a row is 1 in 36.
2 aces is one in 220.
Correct (in every answer):
Flip 5 tails in a row: You have a 1 in 2 chance each flip. 1/25 = 1/32
Roll snake eyes: you have a one in 6 chance on each die. 1/62 = 1/36
Roll a 7 twice in a row: 1/62 = 1/36
Get dealt 2 aces: There are 4 aces out of 52 cards to start so the chance of the first card being an ace is 4/52 and the chance the second card will be an ace is 3/51 since we have dealt one card and we're assuming it was the ace. So total odds are 4/52 * 3/51 = 1/220
