a card is drawn from a well shuffled deck of 52 cards .find(p drawing an ace or a 9)

5/52 is that correct?

Aren't there 4 aces and 4 9's ?

So how many different cards satisfy your condition?

To find the probability of drawing an ace or a 9 from a well-shuffled deck of 52 cards, we need to determine the number of favorable outcomes (number of aces and 9s) and the total number of possible outcomes (52 cards).

Number of favorable outcomes:
There are 4 aces (one ace in each suit: hearts, diamonds, clubs, and spades) and 4 9s (one 9 in each suit). So, there are a total of 4 + 4 = 8 favorable outcomes.

Total number of possible outcomes:
In a deck of 52 cards, there are no duplicates, so the total number of cards is 52.

Therefore, the probability of drawing an ace or a 9 is given by:
Probability = (Number of favorable outcomes) / (Total number of possible outcomes)
Probability = 8/52

Simplifying the fraction, we get:
Probability = 2/13

So, the correct probability of drawing an ace or a 9 is 2/13, which is equivalent to 0.1538 or approximately 15.38%.
