(iii) The probability of an event (other than sure and impossible event) lies between ........ (iv) Every elementary event associated to a random experiment has ....... probability. (v) Probability of an event A+ Probability of event ' not\ A ' =......... (vi) Sum of the probabilities of each outcome in an experiment is ........

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

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

The probability that an event A happens in one trial of an experiment, is 0.4 There independent trials of the experiments are performed. The probability that the event A happens atleast once, 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

If the probability of an event E happening is 0.023, then P(overline(E)) =______

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

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.
