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
