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 13 diamonds in a standard deck of 52 cards, and each card has an equal probability of being drawn, we can predict that Rayoni would pick approximately 13/52 (1/4) of the cards as diamonds.

Therefore, out of 170 cards, it is likely that she would pick around 170 * (1/4) = 42.5 diamonds. Since we cannot have half a card, we would round this down to predict that Rayoni would pick around 42 diamonds.
