A party store offers small balloons and large balloons. You can choose from pink, blue, green, and yellow balloons. You can choose from silver, gold, and white ribbons. Use the counting principle to find the number of different ways you can choose a balloon with a ribbon.
There are 2 options for balloon size and 4 options for balloon color, which gives us $2\times 4=8$ total balloon options. For each of the 8 balloon options, there are 3 ribbon options, so the total number of ways to choose a balloon with a ribbon is $8\times 3=\boxed{24}$.
How many ways can six books be arranged on a shelf?
A. 21
B. 120
C. 360
D. 720
The number of ways to arrange $n$ objects in a line is $n!$ (read "$n$ factorial"). $6!=720$, so there are $\boxed{\text{(D)}\ 720}$ ways to arrange 6 books on a shelf.
There are eight girls competing in an ice-skating competition. In how many ways can they finish in first, second, and third place?
A. 336
B. 1,680
C. 2,016
D. 40,320
There are 8 choices for first place, then 7 choices left for second place, then 6 choices left for third place. However, the order in which we choose the winners doesn't matter (e.g. choosing Sarah first, then Anna second, then Betty third is the same as choosing Anna first, then Betty second, then Sarah third), so we must divide by $3!$ (the number of ways to order 3 people) to adjust for overcounting.
Therefore, the number of ways to choose the winners is $\dfrac{8\times 7\times 6}{3!} = \boxed{336}$.

How many ways can a president and vice president be selected from a class of 12?
A. 23
B. 72
C. 132
D. 1,320
There are 12 choices for the first person (the president) and 11 choices left for the second person (the vice president). However, the order in which we choose the two people doesn't matter (e.g. choosing Sarah as president and Anna as vice president is the same as choosing Anna as president and Sarah as vice president), so we must divide by $2$ to adjust for overcounting.
Therefore, the number of ways to choose a president and vice president from a class of 12 is $\dfrac{12\times 11}{2} = \boxed{66}$.
A coin is tossed, and a standard number cube is rolled. What is the probability that the coin shows heads and the number cube shows an even number?
A. start fraction 1 over 6 end fraction
B. 1
C. one-fourth
D. one-half
The probability of the coin showing heads is $\frac{1}{2}$, and the probability of the number cube showing an even number is $\frac{3}{6}=\frac{1}{2}$ (there are three even numbers on a standard number cube: 2, 4, and 6, and there are six equally likely outcomes in total).
By the multiplication principle for independent events, the probability of both events occurring is the product of their individual probabilities: $\frac{1}{2}\times\frac{1}{2}=\boxed{\frac{1}{4}}$.
A bag contains 3 blue marbles, 9 green marbles, and 11 yellow marbles. Twice you draw a marble and replace it. Find P(blue, then green).
A. start fraction 27 over 529 end fraction
B. start fraction 27 over 23 end fraction
C. start fraction 15 over 529 end fraction
D. Start Fraction 12 over 23 End Fraction
The probability of drawing a blue marble on any given draw is $\frac{3}{3+9+11}=\frac{3}{23}$, and the probability of drawing a green marble on any given draw is $\frac{9}{23}$. Because we're replacing the marble after the first draw, the outcome of the first draw has no effect on the probability of the second draw.
By the multiplication principle for independent events, the probability of drawing a blue marble on the first draw and a green marble on the second draw is $\frac{3}{23}\times\frac{9}{23}=\boxed{\frac{27}{529}}$.
