Abox containing pennies, nickels, and dimes has 13 coins with a
total value of 83 cents. How many coins of each type are in the
box? Is the economy productive?
A large pile of coins consists of pennies, nickels, dimes, and
quarters.
(a)
How many different collections of 40 coins can be chosen if
there are at least 40 of each kind of coin?
(b)
If the pile contains only 20 quarters but at least 40 of each
other kind of coin, how many collections of 40 coins can be
chosen?
(c)
If the pile contains only 30 dimes but at least 40 of each other
kind of coin, how...
A jar contains 5 pennies, 4 nickels and 2 dimes. A child selects
2 coins at random without replacement from the jar. Let X represent
the amount in cents of the selected coins. Find the probability X =
10. Find the probability X = 11. Find the expected value of X.
A jar contains 2 pennies, 6 nickels and 4 dimes. A child selects
2 coins at random without replacement from the jar. Let X represent
the amount in cents of the selected coins.
a. Find the probability X = 11.
b. Find the expected value of X

You have a jar containing pennies, nickels, dimes, and quarters.
In how many ways can you select exactly 10 coins if the order in
which you select them does not matter and
1. You have at least 10 of each type of coin available and there
are no restrictions
2. You have at least 10 of each type of coin available and you
need to select at least two dimes and two nickels
3. You have at least 10 pennies,...
Is it possible to have 60 coins, all of which are pennies, dimes
or quarters, with a total worth $3. List all possibilities.
Please fully explain each step.
A box contains 4 quarters, 3 dimes, and 2 nickels.
a. Two coins are selected at random without replacement one at a
time. Compute the probability that the first coin is a dime and the
second is a nickel.
b. Three coins are selected at random with replacement. Compute
the probability that at least one of them is a nickel.
c. Construct a probability distribution of the number of
quarters selected for a procedure of selecting three coins without
replacement....
