Question

suppose you have a bag of 7 coins, 3 nickels and 4 dimes. two coins are drawn at random without replacement. if the first coin is a nickel what are the chances the second coin will be a dime?

Answer 1

Answer: 2/3

Step-by-step explanation:

The nickel is not put back, so there are 7-1 = 6 coins left. Of those, 4 are dimes.

4/6 = 2/3 is the fractional probability of getting a dime on the second selection.
