A coin jar contains 12 quarters, 15 dimes, and 23 nickels. Find the probability that a Karen will choose a dime from the jar and then Mikah will choose a quarter from the jar.

6/25 is incorrect

Respuesta :

Answer:

18/245.

Step-by-step explanation:

Total number of coins = 12+15+23 = 50.

Prob(Karen chooses a dime) = 15/50 = 3/10.

Prob(Mikah then chooses a quarter) = 12/49.  ( Karen has already removed one coin)

Prob(of Karen choosing a dime then Mikah a quarter)

= 3/10 * 12/49

= 36/490

= 18/245.
