Question 1166183: Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following:
6 Pennies 7 Dimes
16 Nickels 19 Quarters
What is the probability that you reach into the jar and randomly grab a penny and then, without replacement, a dime? Express your answer as a fraction or a decimal number rounded to four decimal places. Answer by themasterofcircuits(27) (Show Source):
You can put this solution on YOUR website! We have 6 pennies, 7 dimes, 16 nickels, and 19 quarters.
The total number of coins in the jar is 6+7+16+19= 48 coins
The probability of selecting a penny randomly is =
Since we do NOT replace the penny, we now have 47 coins in the jar.
The probability of selecting a dime is
Since these two events are independent of each other: P(AB)=P(A)*P(B)
P(AB) = *= or 0.0186 or 1.86%
