Basic Statistics & Probability True or False

1. A die was rolled and a card was drawn from a standard deck 50 times. The number on the die and the suit of the card were recorded in a bar graph (1C means rolling a one and drawing a club).

C = clubs
D = diamonds
H = hearts
S = spades

What is the experimental probability of drawing a heart? -> 8%
2. A die was rolled and a card was drawn from a standard deck 50 times. The number on the die and the suit of the card were recorded in a bar graph (1C means rolling a one and drawing a club).

C = clubs
D = diamonds
H = hearts
S = spades

How does the experimental probability of rolling a 1 compare to the theoretical probability of rolling a 1? -> The theoretical probability is higher.
3. A die was rolled and a card was drawn from a standard deck 50 times. The number on the die and the suit of the card were recorded in a bar graph (1C means rolling a one and drawing a club).

C = clubs
D = diamonds
H = hearts
S = spades

How does the experimental probability of rolling a 1 and drawing a diamond compare to the same theoretical probability? -> The theoretical probability is higher.
4. Poppy has five dresses, four hoodies, and three pairs of shoes to choose from. How many different outfits can she make from these choices (no matter how hideous they might be)? -> 70
5. If you roll two dice and find the product, what is the probability that the product will be greater than 24? -> ≈ 12%
6.

If you randomly choose a coin from this bank, what is the probability that it will be silver and worth less than a dime? -> 62.5%
7.

If you randomly choose a coin from this bank, what is the probability that it will be silver or worth less than a dime? -> 100%
8. Travis, John, Claire, and Sophie are deciding who among them will be President, Vice President, Secretary, and Treasurer for the yearbook club. How many ways could we arrange these four students in these four spots? -> 120
9. If a card is chosen at random from a standard deck of cards, what is the probability that the card will be an ace OR a spade? -> 12.5%
10. Your dad bought three different flavors of ice cream (chocolate chip cookie dough, double chocolate fudge, and bubblegum). If he makes you a bowl with two different flavors, what is the probability that both flavors will contain chocolate?
