### Probability Exercise: Drawing MarblesElias has a jar containing 15 black marbles, 8 red marbles, and 9 white marbles. He will perform the following experiment twice:1. Randomly choose a marble from the jar.2. Record its color.3. Replace the marble back into the jar.He will then choose a second marble and record its color.#### Question:What is the probability of choosing a black marble first and then a red marble on the second draw?### Answer Options:- \( \frac{15}{24} \)- \( \frac{9}{128} \)- \( \frac{135}{1024} \)- \( \frac{15}{128} \)To find the correct answer, it is important to note:1. The total number of marbles is \( 15 + 8 + 9 = 32 \).2. The probability of drawing a black marble first is \( \frac{15}{32} \).3. Since the marble is replaced, the second draw also consists of 32 marbles.4. The probability of drawing a red marble next is \( \frac{8}{32} \).Thus, the combined probability:\[ P(\text{Black, then Red}) = P(\text{Black}) \times P(\text{Red}) \]\[ P(\text{Black, then Red}) = \frac{15}{32} \times \frac{8}{32} = \frac{120}{1024} = \frac{15}{128} \]### Final Answer:\[ P(\text{Black, then Red}) = \frac{15}{128} \]Hence, the correct option is:- \( \boxed{\frac{15}{128}} \)
