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.

Based on the probability of drawing a diamond from a standard deck, which is 1/4 or 25%, we can predict that Rayoni would pick approximately 42.5 diamonds if she drew 170 cards. However, since you cannot have half a card, we can round this number to either 42 diamonds or 43 diamonds.
