Probability of a impossible event is …………

Fill in the blacks: (i) The probability of an impossible event is ………. . (ii) The probability of a sure event is …….. . (iii) For any event E, P(E ) + P(not E)=……… . (iv) The probability of a possible but not a sure event lies between .......... and ......... . (v) The sum of probabilities of all the outcomes of an experiment is ......... .

Probabilityi of an impossible event is:

Probability of impossible events is zero.

Assertion : A die is thrown. Let E be the event that number appears on the upper face is less than 1, then P( E) = 1/6 Reason : Probability of impossible event is 0.

Vinneta said that probability of impossible events is 1, Dhanalakshmi said that probability of sure event is '0' and Sireesha said that probability of any event lies in between 0 and 1. In the above with whom will you agree?

In two independent events the probability of happening one event is 2/7 and probability of happening of second event is 1/5 . Find the probability of happening of both events.
