In Ms. Q's deck of cards, every card is one of four colors (red, green, blue, and yellow), and is labeled with one of seven numbers (1, 2, 3, 4, 5, 6, and 7). Among all the cards of each color, there is exactly one card labeled with each number. The cards in Ms. Q's deck are shown below.
Yunseol draws 5 cards from Ms. Q's deck. What is the probability that three cards have the same number?
The probability that three cards have the same number is 1/35. This is because there are 7 possible numbers, and each number appears only once in each color. Therefore, there are 7 x 4 = 28 cards in the deck, and the probability of drawing three cards with the same number is 1/28 x 1/27 x 1/26 = 1/35.
Your solution presentation is absolutely atrocious bullshit.
All of your probability solutions presentations are atrocious bullshit, except for the posts where you’ve plagiarized, and those are not your solutions.
Are you a troll, or just a self-deluded idiot?
