You have a penny, a nickel, a dime, a toonie, and a loonie. How many different (non-zero) sums of money can you produce?
You have a penny, a nickel, a dime, a toonie, and a loonie. How many different...
The question is: How many different sums of money can be made using one or more of a penny, a nickel, a dime and a quarter? My question is: I was thinking that this was a permutation problem and since I can use one or more that permutation would be P(4,4) = 24. However, that was incorrect. My second idea was that it is a combination problem because the sums have to be different. Please help

21. How many different sums of money can you make with three pennies, a nickel, a dime, and two quarters?
Enter a fraction in simplest form. A penny, nickel, dime, and quarter are flipped together. All the coins are fair. The probability of the event "Tails" for the penny, "Heads" for the nickel, "Heads" for the dime, and "Heads" for the quarter is A
In the United States Coins like the dime, quarter and half dollar have a nickel rich surface and copper rich core. Using principles of diffusion, explain how these three layers are bonded together.
Imagine you have one quarter, one nickel, and one penny in your wallet. What is the sample space if we were to grab one coin from your wallet? Let S represent the sample space for this question.
Problem 2 Suppose you flip a penny and a dime. Each coin is equally likely to come up heads and tails. The two flips are independent a) What is the sample space? b) What is the conditional probability that both coins come up heads, given that the penny comes up heads? c) What is the conditional probability that both coins come up heads, given that at least one of the coins comes up heads? (Hint: the answers in part (b)...

Suppose you have an animal with 10 different olfactory receptor proteins. 1. Approximately how many different odors can this animal distinguish? 2. How many different types of olfactory receptor neurons can you expect this animal to have? 3. This animal has a sensitive sense of smell- it can smell odors at low concentrations. Approximately how many olfactory receptor neurons would you expect this animal to have? 4. How many different type of olfactory bulb glomeruli would you expect this animal...
