We are given a key pad assuming that the numbers are of 10 options from 0 to 9. IN thsi case, guessing the 3 digit pin number can be determined via counting method. The first number has 10 options so as second and third. Hence the total number of options is 10^3 or 1000. The probability of getting the pin teh first time is 1/1000 or 0.001.

five years ago, sarah's aunt was 4 times older than sarah. if sarah's aunt is 42 years older then sarah, then sarah, how ols is
Nimfa-mama [501]

Answer:

Therefore, Sara’s current age (5 years later) is 19 years old.

Step-by-step explanation:

Let xx be Sara’s age five years ago. Therefore, Sara’s aunt’s age 5 years ago is 4x4x.

The difference in their ages is a constant, no matter how many years have gone by. (Can you see why?)

4x−x=42

3x=42

x=42/3

x=14

14+5=19

Therefore, Sara’s current age (5 years later) is 19 years old.
