Yuto has a bag containing 3 red marbles, 5 blue marbles, 2 green marbles, and 8 yellow marbles. Rin
reaches into the bag, pulls out a blue marble, and puts it in her pocket. Then Misaki reaches in and pulls
out a marble. What is the total number of possible outcomes for Misaki's marble? - Answers 17

Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red.
The other half were black. Josh predicted that he would choose a red card in 4 out of 8 trials. When he
conducted the experiment, he actually chose a red card 6 out of 8 times. Which explains the most likely
reason for the discrepancy between Josh's predicted and actual results? - Answers He used too few trials
for the sample space.
, A set of cards contains cards numbered 1 - 8. Mrs. Jacob's class is conducting an experiment in which a
card is drawn from the pile, the number is recorded, and then the card is returned to the set. The class
will conduct 1,000 trials. Based on the theoretical probability, which is the best prediction for the
number of times a 4 will be drawn from the pile? - Answers 125
The theoretical probability of an event occurring is mc003-1.jpg. Which best describes the experimental
probability associated with this event? - Answers Out of every 5 trials, the desired outcome will occur
approximately 2 times.
Jonas is conducting an experiment using a 10-sided die. He determines that the theoretical probability of
rolling a 3 is mc015-1.jpg. He rolls the die 20 times. Four of those rolls result in a 3. Which adjustment
can Jonas make to his experiment so the theoretical and experimental probabilities are likely to be
closer? - Answers He can increase the number of trials.
Mai conducted an experiment by flipping a fair coin 200 times. The coin landed heads up 110 times.
Which statement about the coin landing heads up in Mai's experiment is correct? - Answers The
experimental probability of the coin landing heads up is 11/20 and the theoretical probability of the coin
landing heads up is 1/2
Frederick designed an experiment in which he spun a spinner 20 times and recorded the results of each
spin. - Answers unknown lol
Elijah is going to spin a spinner 180 times. - Answers Elijah's prediction is high because 180 x 1/4 = 45
Four students each flip a coin multiple times and record the number of times the coin lands heads up.
The results are shown in the table.
Which student is most likely to find that the actual number of times his or her coin lands heads up most
closely matches the predicted number of heads-up landings? - Answers Collin
James conducted an experiment with 4 possible outcomes. He determined that the experimental
probability of event A happening is 10 out of 50. The theoretical probability of event A happening is 1
out of 4. Which action is most likely to cause the experimental probability and theoretical probabilities
for each event in the experiment to become closer? - Answers completing the experiment many more
times and combining the results to the trials already done
A bag contains 1 red tile, 1 blue tile, 1 green tile, 1 yellow tile, and 1 purple tile. Kaison chooses a tile
from the bag, records its color, and then replaces the tile. She repeats this procedure a total of 50 times.
Her results are shown in the table.
How does the experimental probability of choosing a yellow tile compare with the theoretical
probability of choosing a yellow tile? - Answers The experimental probability is the same as the
theoretical probability.
