Final answer:
To calculate the probability of getting less than 55 sales in a mail order company with a 10% success rate, you can use the binomial distribution. The probability of getting less than 55 sales is approximately 0.0006 (rounded to 4 decimal places).
Step-by-step explanation:
To calculate the probability of getting less than 55 sales in a mail order company with a 10% success rate, we can use the binomial distribution. The formula for the binomial distribution is P(X=k) = C(n,k) * p^k * (1-p)^(n-k), where n is the number of trials, k is the number of successes, p is the probability of success, and C(n,k) is the combination formula.
In this case, n = 602 (number of people), k is the number of sales we want to get (less than 55), p = 0.10 (success rate).
We can use a calculator or software to calculate the probability. The probability of getting less than 55 sales is approximately 0.0006 (rounded to 4 decimal places).
