Question

You cannot remember your 4-digit bike-lock combination. What is the probability that you guess the combination correctly? (Enter your probability as a fraction.)
=_________

Answer 1

1/10000 every try














..................

Answer 2

The probability of correctly guessing the combination will be the quotient between one and the total number of combinations of the lock.

Here we will find that the probability is P = 1/10,000

So the first thing we need to do is find the total number of combinations of the lock.

We know that it is a 4-digit bike lock.

For each on of these 4 digits, we have 10 options (1, 2, 3, 4, 5, 6 , 7, 8 , 9) and the total number of combinations will be given as the product between all the numbers of options.

Then the total number of combinations is:

C = 10*10*10*10 = 10,000

Then the probability of guessing the combination correctly is:

P = 1/10,000
