Their is only 1 nickel and 6 coins. 2 quarters worth $0.50, one dime worth $0.10, one nickel worth $0.05, and two pennies worth $0.02. Therefore there is 1/6 six chance she will draw a nickel first. Now there are 5 coins and 2 of them are quarters which means there is a 2/5 chance of drawing a quarter.
