#5 Find the probability
![**Educational Website: Probability and Sales Conversion**
**Understanding Sales Conversion through Probability**
The success rate a salesman may achieve through cold calling will largely depend on the approach they take. According to Charlie Cook, author and marketing consultant, conversion rates for cold calls usually fall in the 2 percent range, while referrals may have a 50 percent conversion and solid leads may have a 20 percent conversion. A group of salesmen was assigned to pursue 250 "solid leads" during the period of a week.
### Exercises
1. **Probability Distribution of Sales**
- Let \( X \) be the number of sales generated from 250 "solid leads." Describe the distribution of \( X \) and its parameters:
\[
X \sim \text{Select an answer} \, (n = \_\_, p = \_\_)
\]
2. **Express Probability Symbolically**
- Use the random variable notation to symbolically express the probability that at most 56 sales will be generated from 250 "solid leads":
\[
P(X \leq 56) = \text{Select an answer}
\]
3. **Normal Approximation**
- Let \( Y \) be a normal variable that will be used to approximate the probability in question. Find the parameters of \( Y \) (round the answers to 2 decimal places):
\[
Y \sim \text{Select an answer} \, (\mu = \_\_, \sigma = \_\_)
\]
4. **Express Probability Using Normal Approximation**
- Use the random variable notation to symbolically express the approximate probability that at most 56 sales will be generated from 250 "solid leads":
\[
P(Y \leq 56) = \text{Select an answer}
\]
5. **Apply Continuity Correction**
- Use the correction for continuity:
\[
\text{Select an answer}
\]
6. **Calculate Probability**
- Find the probability (round the answer to 4 decimal places):
\[
\_\_
\]
