Use the table to answer the question.
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.
Based on the table, there are 52 cards in a standard deck, and 13 of them are diamonds. This means that the probability of picking a diamond is 13/52, which reduces to 1/4.
If Rayoni draws 170 cards, we can expect that she will pick around 1/4 of those cards to be diamonds. Therefore, 1/4 of 170 is 170/4 = 42.5.
Since you can't have half a card, we would predict that Rayoni would pick approximately 42 diamonds out of 170 cards drawn.
