In a certain city district, the need for money to buy drugs is stated as the reason for 71% of all thefts. Find the probability that among the next 5 theft cases reported in this district, (a) exactly 2 resulted from the need for money to buy drugs. (b) at most 3 resulted from the need to buy drugs. (a) Find the probability that among the next 5 theft cases reported in this district, exactly 2 resulted from the need for money to buy drugs. P(X=2)= (Round to three decimal places as needed.) (b) Find the probability that among the next 5 theft cases reported in this district, at most 3 resulted from the need to buy drugs. P(X≤3) = (Round to three decimal places as needed.)

**Probability Problems Related to Need for Money to Buy Drugs and Theft Cases**

In a certain city district, the need for money to buy drugs is stated as the reason for 71% of all thefts. Below are two problems for you to solve based on this statistic:

1. **Exactly 2 out of the Next 5 Theft Cases:**
   Find the probability that among the next 5 theft cases reported in this district, exactly 2 resulted from the need for money to buy drugs.
   
   **(a) Find the probability that among the next 5 theft cases reported in this district, exactly 2 resulted from the need for money to buy drugs.**
   
   \[
   P(X = 2) = \quad \text{(Round to three decimal places as needed.)}
   \]

2. **At Most 3 out of the Next 5 Theft Cases:**
   Find the probability that among the next 5 theft cases reported in this district, at most 3 resulted from the need to buy drugs.
   
   **(b) Find the probability that among the next 5 theft cases reported in this district, at most 3 resulted from the need to buy drugs.**
   
   \[
   P(X \leq 3) = \quad \text{(Round to three decimal places as needed.)}
   \]

These calculations typically require using the binomial probability formula or a binomial probability distribution table.
