There are 10+14+6=30 total coins in the bag including 10 pennies,14 buckles and 6 dimes Then, P(removing a penny after first pick): 10/30 or 1/3 Now, there are only 9 pennies, and total amount of coins decrease by one count which is 29 P(remove a nickel after second pick): 14/29 Now, there are only 28 coins in total left in the box, so P(removing a dime): 6/28 or 3/14 Lastly, to find the probability or compound event, take: 1/3×14/29×3/14=42/1638 Simplify 42/1638 21/819. As a result, the probability you remove a penny and nickel and a dime in that order is 21/819. Hope it help!
