How many three-digit numbers can you create using only the digits 6, 7, 8, and 9 if each digit cannot be repeated in any three-digit number (all digits must be different)?

24

Step-by-step explanation:

We are solving for variation (without repitition)

n = 4 digits (6,7,8,9)

p = 3 digits no.

variation = nfactorial/ (n-p) factorial.

4x3x2x1/(4-3)factorial = 24/1

= 24.

there are 24 3-digit number you can select from 6,7,8,9 without having a recurring number.

profit of $140,910

there is a missing number I will assume that the probability is 1 in 11,000

company expected revenue per policy = $600

companies expected expense = 400,000 * (1/11,000) = -36.36

profit per policy = $536.64

$536.64*250 = $140,910
