Answer to Problem 11IP
Explanation of Solution
Given :
Odell has the same number of quarters, dimes, and nickels. In all he has $4 in change.
In order to find how many of each coin does he have, first a quarter is 25cent , a dime is 10 cent, and a nickle is 5 cent, $4 is equal to 400 cent . If x is the number of quarters, then 25x is the value, in cent similarly for dimes 10x and for nickle is 5x , then adding them equal to 400 cent, then solving it as shown below:
So, Odell has 10 of each type of coin.
ways can at least one counter with side A occur, there are 6 possible outcomes (front and back) and the counters so,
Now, 2 out of 6 are A, so 2/6 or 1/3 chance.
So, side A occurs in 6 ways.
