There has to be at least 1 penny in the sack.
There has to be at least 2 dimes in the sack.
There has to be at least 3 nickels in the sack.
The least number of coins in the sack is 6.
This is equal to the number of coins stated to be in the sack.
This means that exactly 1 penny, 2 dimes, 3 nickels are in the sack.
The probability of getting a nickel out of the sack is 3/6 which is the same as 1/2 so your answer appears to be d.
