Final answer:
The odds of drawing a heart or a spade from a standard deck of playing cards is 1/2.
Step-by-step explanation:
To find the odds of each outcome if a card is drawn from a standard deck of playing cards, we need to determine the probability of each outcome.
In this case, the event of drawing a heart or a spade is mutually exclusive, meaning a card cannot be both a heart and a spade at the same time.
There are 13 hearts and 13 spades in a deck of 52 playing cards.
The total number of outcomes is 52 because there are 52 cards in the deck.
The probability of drawing a heart is 13/52, and the probability of drawing a spade is also 13/52.
Since the events are mutually exclusive, we can add the probabilities to find the probability of drawing a heart or a spade, which is (13/52) + (13/52) = 26/52 = 1/2.
