A card is drawn from a well shuffled deck of 52 cards. Find P (drawing an acre or a 9)
there are 4 aces and 4 9s
therfore there are 8 total chances
so 8/52
when i learned it , if it said "or" you add the chance
if it said "and" you multiply
To find the probability of drawing an ace or a 9 from a well-shuffled deck of 52 cards, we first need to determine the number of favorable outcomes and the total number of possible outcomes.
The total number of possible outcomes is the total number of cards in the deck, which is 52.
Now let's calculate the number of favorable outcomes, which is the number of aces plus the number of 9s in the deck.
The deck contains four aces (one ace of each suit: hearts, diamonds, clubs, and spades) and four 9s (one 9 of each suit). So, we have a total of 4 aces + 4 9s = 8 favorable outcomes.
Now we can use the formula for probability:
P(drawing an ace or a 9) = number of favorable outcomes / total number of possible outcomes
P(drawing an ace or a 9) = 8 / 52
Simplifying the fraction, we get:
P(drawing an ace or a 9) = 2 / 13
Therefore, the probability of drawing an ace or a 9 from a well-shuffled deck of 52 cards is 2/13.
