If 2/(11) is the probability of an event, what is the probability of the event not A

The probability of happening an event A in one trial is 0.4. Find the probability that the event A happens at least one in three independent trials.

The probability of happening an event A in one trial is 0.4. Find the probability that the event A happens at least one in three independent trials.

The probability of an event A occuring is 0.5 and of B is 0.3 If A and B are mutually exclusive events , then find the probability of neither A nor B occurring.

Can the probability of an event be -2 ? Give reason

The probability of an event A occurring is 0.5 and of B is 0.3. If A and B are mutually exclusive events then the probability of neither A nor B occurring is

A and B are two independent events such that their probabilities are (3)/(10) " and " (2)/(5) respectively. The probability of exactly one of the events happening, is
