Question

A woman's change purse contains a quarter, two dimes and two pennies. What is the probability that a coin chosen at random will be worth at least ten cents?

• A. $\frac{1}{5}$
• B. $\frac{2}{5}$
• C. $\frac{3}{5}$
• D. $\frac{4}{5}$

Answer 1

The correct option is C $\frac{3}{5}$

$1$ quarter $=25$ cents , $1$ dimes $=10$ cents , $1$ penny $=1$ cent
We can select $1$ coin in $5$ ways.
Selecting a coin such that the coin will worth atleast $10$ cents is $1+2=3$.
Therefore, the probability is $\frac{3}{5}$.
