First of all, lets ask ourselves how we are going to get Mary's marbles. In the problem, we can see that Joan has 15 times as many marbles as mary. So this means that Mary's marbles are multiplied to 15 in order to get Joan's marbles (which happens to be 45). So if we reverse the situation, then in order to get Mary's marbles, you are going to have to divide Joan's marbles by 15. Since we know that Joan has 45 marbles, we divide that by 15. The answer is 3. Mary has a total of 3 marbles.
The possible outcomes is 6 because it has 6 sides
Answer:
37044 different combinations of 4 movies can he rent if he wants at least one comedy
Step-by-step explanation:
The order in which the movies are selected is not important, so we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
How many different combinations of 4 movies can he rent if he wants at least one comedy
The easier way to solve this is subtract the total from the number of combinations with no comedies.
Total:
4 movies from a set of 14 + 19 = 33. So
No comedies:
4 movies from a set of 19.
At least one comedy:
40920 - 3876 = 37044
37044 different combinations of 4 movies can he rent if he wants at least one comedy
