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.
Since there are 52 cards in a standard deck and there are 13 diamonds in the deck, the probability of picking a diamond is 13/52 = 1/4.
If Rayoni draws 170 cards, we can expect her to pick approximately (1/4) * 170 = 42.5 diamonds.
Since we cannot have a fraction of a card, we can round this number to the nearest whole number. Thus, we can predict that Rayoni would pick about 43 diamonds if she drew 170 cards.
