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
If we assume that Rayoni is drawing cards randomly and that there are 13 diamonds in a standard deck of 52 cards, the probability of drawing a diamond on any given draw is 13/52 = 1/4.
If she draws 170 cards, we can predict that she would pick approximately 170 * 1/4 = 42.5 diamonds.
Since she can't pick half a card, we would round this down to predict that Rayoni would pick around 42 diamonds if she drew 170 cards.
