Suit Number
Clubs 7
Diamonds 12
Hearts 8
Spades 13

Rayoni pulled cards from a standard deck. She picked a card, recorded the suit, and put it back. She repeated the process many times. Predict how many diamonds she would pick if she drew 170 cards.

Answer 1

To predict how many diamonds Rayoni would pick if she drew 170 cards, we can use the probability of drawing a diamond from the deck.

There are a total of 52 cards in a standard deck, with 13 of them being diamonds.

The probability of drawing a diamond is:
Number of diamonds / Total number of cards = 13/52 = 1/4

Therefore, in 170 cards, Rayoni can expect to pick approximately:
170 * (1/4) = 42.5

Since Rayoni cannot pick a fraction of a card, we can predict that she would pick about 42 or 43 diamonds in 170 draws.
