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

Answer:
C) 4
Step-by-step explanation:
Given equation:
The above equation represents proportional relationship.
To find the constant of proportionality.
Solution:
<em>The equation representing proportional relationship is given by:</em>
<em>
</em>
<em>where 
represents constant of proportionality.</em>
So, in order to find the value of for the given proportionality relationship, we will solve for 
We have:
Solving for
Dividing both sides by 2.
∴ 
Thus, the constant of proportionality = 4.
