Answer:
64
Explanation:
There are 4 options to choose from:
Each has a 1/4 chance of being picked.
For 3 times in a row, we would multiply the chance of being picked for one option, by whatever the other option's chance is.
As they all have the same chance, and it is 3 times in a row, we would do the following:
1/4 x 1/4 x 1/4
This is:
1/16 x 1/4
Which is:
1/64
Therefore, any possible combination has a 1/64 chance of occurring, meaning that there are 64 possible combinations that could be created.
