Lucy has a deck of 52 cards with 4 suits (hearts, spades, diamonds, and clubs), and each suit has cards numbered 1–13. What is the complement of her not picking a 4 from the deck of cards? Te answer should be a fraction. Remember to simplify.
There are 13 fours in a deck of cards (one for each suit), so the probability of picking a 4 is 13/52.
The complement of not picking a 4 is picking any card that is not a 4. There are 52 total cards in the deck, and 13 of them are fours. So, there are 52 - 13 = 39 cards that are not a 4.
Therefore, the probability of not picking a 4 is 39/52.
The complement of not picking a 4 is the probability of picking a 4, so the answer is 13/52, which simplifies to 1/4.
wrong
I apologize for the mistake. Let's correct it.
The probability of not picking a 4 from the deck of cards is the number of cards that are not 4 divided by the total number of cards.
There are 52 total cards in the deck, and there are 13 cards that are 4 (one in each suit).
So, there are 52 - 13 = 39 cards that are not a 4.
Therefore, the probability of not picking a 4 is 39/52.
The complement of not picking a 4 is the probability of picking a 4, which would be 1 - 39/52 = 13/52.
So, the complement of not picking a 4 from the deck of cards is 13/52, which simplifies to 1/4.
