Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
Desired outcomes:
2 components which function properly, from a set of 5. So
Total outcomes:
2 components, from a set of 6. So
Probability:
66.67% probability that all selected components function properly
