Answer:
0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Probability of grabbing a nickel:
19 nickels out of 17+10+19+23 = 69 coins, so:
![P(A) = \frac{19}{69}](https://tex.z-dn.net/?f=P%28A%29%20%3D%20%5Cfrac%7B19%7D%7B69%7D)
Probability of grabbing a penny, considering the first coin grabbed was a nickel:
17 pennies out of 68 coins. So
![P(B|A) = \frac{17}{68} = \frac{1}{4}](https://tex.z-dn.net/?f=P%28B%7CA%29%20%3D%20%5Cfrac%7B17%7D%7B68%7D%20%3D%20%5Cfrac%7B1%7D%7B4%7D)
What is the probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny?
![P(A \cap B) = P(A)P(B|A) = \frac{19}{69} \times \frac{1}{4} = \frac{19}{69*4} = 0.0688](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%20P%28A%29P%28B%7CA%29%20%3D%20%5Cfrac%7B19%7D%7B69%7D%20%5Ctimes%20%5Cfrac%7B1%7D%7B4%7D%20%3D%20%5Cfrac%7B19%7D%7B69%2A4%7D%20%3D%200.0688)
0.0688 = 6.88% probability that you reach into the jar and randomly grab a nickel and then, without replacement, a penny.
