Grant has been saving coins each day for a week. In his drawer, he has 8 quarters, 9 dimes, 6 nickels, and 7 pennies. If he picks two coins without replacing them, what is the probability he will pick two nickels?

P_(2nickles)=(P_(first=nickle)) * (P_(second=nickle))

P_(2nickles)=(nickle)/(total) *(nickle)/(total)

P_(2nickles)=(6)/(30) *(5)/(29)

P_(2nickles)=(30)/(870) \approx 3.44\%
