Question

Rest of question: Shelly recreated an experiment in which the probability of drawing a red card from a stack of red, blue, yellow, and purple cards is She draws a card, records it, replaces it, and then draws another card and continues this procedure 100 times. At the end of her experiment she notices that she has drawn a red card 33 times. Which of the following statements is true about Shelly’s experiment?

 

A: Shelly’s deck of cards contains more red cards.

B: Shelly’s results are the same as the predicted results.

C: Shelly’s results are higher than the predicted results.

D: Shelly’s results are lower than the predicted results.

Answer 1

There are four colors. If the probability of any color is 25% or 1/4 = 0.25, then the predicted number of red in 100 draws is 25 red. If she recorded 33, then that's higher than the predicted results.
