1/3

What is the probability of drawing either an Ace or a Hearts from a standard 52-card deck?
16/52 or 4/13 (using the addition rule: 4/52 + 13/52 - 1/52 = 16/52 = 4/13)
200
If you roll two standard 6-sided dice, what is the probability that both dice show an even number?
9/36 or 1/4 (each die has 3 even numbers, so 3/6 x 3/6 = 9/36 = 1/4).

In Monopoly, if you are in jail and must roll doubles to escape on your turn, what is the probability that you successfully roll doubles on that attempt?
6/36 or 1/6 (out of 36 total outcomes for two dice, only [1,1], [2,2], [3,3], [4,4], [5,5], and [6,6] are doubles).
300
Using a standard 40-card Uno deck (numbers 0 to 9 across 4 colors, with no wildcards), what is the probability of drawing either a Red card or an even-numbered card?
25/40 or 5/8 (10 Red cards + 20 even-numbered cards minus the 5 Red even-numbered cards that overlap: (10 + 20 - 5) / 40).
300
If you roll two dice and their sum is 8, what is the probability that at least one of the dice rolled a 5?
2/5 (Out of the 5 possible pairs that sum to 8—[1,7 doesn't exist]—only (3,5) and (5,3) contain a 5).

In The Game of Life, the spinner has numbers 1 through 10. If you spin the wheel, what is the conditional probability that you spin a number greater than 7 given that the number you spun is even?
2/5 or 40% (the even numbers on the spinner are {2, 4, 6, 8, 10}, and among those, the ones greater than 7 are 8 and 10).
