Find the greatest common factor of the numerator and denominator and divide both by that number
Answer:
Correct option: A -> 10/91
Step-by-step explanation:
If the password has only one number, it has three characters.
So first we can do a combination of 4 choose 3, as the characters and numbers can be at any position, then we multiply by the probability of each space having a character or number:
Combination of 4 choose 3: 4!/3! = 4
First character: 6 possibilities over a total of 16: 6/16 = 3/8
Second character: 5 possibilities over a total of 15: 5/15 = 1/3
Third character: 4 possibilities over a total of 14: 4/14 = 2/7
First number: 10 possibilities over a total of 13: 10/13
Probability: 4 * (3/8) * (1/3) * (2/7) * (10/13) = (2*5)/(7*13) = 10/91
