A combination lock requires a user to select three numbers to unlock it, where all three numbers are between 1 to 30, inclusive,
Sonbull [250]

Answer:

\frac{1}{270}=0.00370

Step-by-step explanation:

As the numbers are only between 1 and 30

Total number of possible combinations = 30×30×30 = 27000

If there are 100 attempts then

\text{P (someone guesses correct)}=\frac{\text{Number of attempts}}{\text{Total number of possible combinations}}\\\Rightarrow \text{P (someone guesses correct)}=\frac{100}{27000}\\\Rightarrow \text{P (someone guesses correct)}=\frac{1}{270}=0.00370

∴ Probability someone can guess the correct combination given 100 attempts is \mathbf{\frac{1}{270}=0.00370}
