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. (1 point)

To predict how many diamonds Rayoni would pick if she drew 170 cards from a standard deck, we can use the concept of probability.

In a standard deck of cards, there are 52 cards, and 13 of them are diamonds.

To find the expected number of diamonds Rayoni would pick if she drew 170 cards, we can calculate the following:

Expected number of diamonds = (Total number of cards) * (Probability of drawing a diamond card)

Expected number of diamonds = 170 cards * (13/52) = 42.5

Therefore, we can predict that Rayoni would pick approximately 43 diamonds if she drew 170 cards from a standard deck.

A pizza parlor owner knows they sell 3 slices of cheese pizza out of 20 total slices sold. Predict how any slices of cheese pizza will be sold if the pizza parlor sells 5,680 total slices in a week. (1 point)

To predict how many slices of cheese pizza will be sold if the pizza parlor sells 5,680 total slices in a week, we can use a similar approach as in the previous question.

Given that 3 slices of cheese pizza are sold out of 20 total slices sold, the probability of selling a slice of cheese pizza is 3/20.

To predict the number of cheese pizza slices that will be sold if 5,680 total slices are sold in a week, we can calculate:

Expected number of cheese pizza slices = (Total number of slices) * (Probability of selling a cheese pizza slice)

Expected number of cheese pizza slices = 5,680 slices * (3/20) = 852

Therefore, we can predict that approximately 852 slices of cheese pizza will be sold if the pizza parlor sells 5,680 total slices in a week.

A student had a spinner and a coin. The student was running an experiment for math class. The spinner had an equal chance of landing on 4 colors: yellow, red, blue, and green. The student flipped the coin and spun the spinner, and the results are recorded in the table.

If the student were to flip the coin and spin the spinner 130 times, how many times would the result be tails and red?
