Hammond Akuma explains the concept of the complement of an event in probability, denoted as E prime. The video covers the universal set, sample space, and how the probability of an event and its complement sum to one. Two examples are provided: calculating the complement probability for months starting with A or J, and for vowels in the alphabet. The video concludes with a reminder to subscribe and ask questions.
