Question from Michelle, a student: Three coins are chosen at random from a purse containing 6 dimes & 4 quarters. What is the probability that the selection will contain at least one quarter? |
Hi Michelle,
I'll give you a hint to get you started.
The probability that the selection will contain at least one quarter is 1 minus the probability that the selection will contain no quarters.
Does this help?
Write back if you need more help.
