Answer
$\frac{2}{7}$
Work Step by Step
To find the probability, first add up all the coins in the purse.
$2$ $+$ $2$$+$ $3$ $=$ $7$
Then see how many nickels are in the purse: $2$.
So the probability would be the number of nickles in the purse over the number of total coins in the purse: $\frac{2}{7}$
