Using it's concept, it is found that the probability of guessing the right combination in one try’s is of 
.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 4 dials, each with a 
probability of getting it correct, hence the probability of getting the right combination is given by:
