Question

A locker combination contains four digits. Each digit can be from 0 through 9. What is the probability that a 4-digit combination chosen at random is made up of 4 digits that are all greater than 6 if each digit can be repeated? 1. Find the total number of possible outcomes. 1. (10)(10)(10)(10) 2. Find the number of favorable outcomes. 2. (3)(3)(3)(3) 3. Use the formula 3. P (event) = Number of favorable outcomes Number of possible outcomes

Hope this helps!!!

Answer 2

Answer: .81%

Explanation:

Since each digit has to be greater than 6, that leaves only 7, 8, & 9 as successful digits.

`Probability = (successful)/(total\ possible)=(3* 3* 3* 3)/(10* 10* 10* 10)=(81)/(10,000)=.0081=.81\%`
