Answer:
The probability that A occurs at least once in three trials = 0.784
Step-by-step explanation:
The probability that an event A occurs in a single trial of an experiment is 0.4
The probability that an event A does not occurs = 1 - 0.4 = 0.6
The probability that A occurs at least once in three trials
=> 1 - A does not occur in any event
Probability A does not occure in any event = 0.6³ = 0.216
The probability that A occurs at least once in three trials = 1 - 0.216
= 0.784
option B is correct
