Probability of an event:
Probability is a measure of the likelihood of an event occurring. It is expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty.

Given information:
The probability of the happening of an event is given as 3/7.

Probability of non-happening:
The probability of the non-happening or the complement of an event is equal to 1 minus the probability of the event occurring.

Calculation:
To find the probability of the non-happening of the event, we subtract the probability of the event occurring from 1.

Probability of non-happening = 1 - Probability of happening
Probability of non-happening = 1 - 3/7
Probability of non-happening = (7/7) - (3/7)
Probability of non-happening = 4/7

Therefore, the probability of the non-happening of the event is 4/7, which corresponds to option 'B' as the correct answer.
