Question 948555
So, 1 penny is 1 cent.
1 nickel is 5 cents.
1 dime is 10 cents.

So let's see how many pairs of coins will get a total value of 7 cents or more.

A penny and a dime will be 11 cents, so that's greater than 7 cents.
A nickel and a dime will be 15 cents, so that's greater than 7 cents.
A penny and a nickel will be 6 cents, but that's less than 7 cents.

So it's possible for either a penny and a dime OR a nickel and a dime to be pulled with a total value of 7 cents or more. 
If it's the nickel and the dime, then the probability is 50%, or 1/2. Hope I helped!
