Complete the statements given below:-

(i) The probability for any event E, P(E) + P(not E) ___________.

(ii) The probability of an event that will never occur is __________. These events are called ________.

(iii) The probability of an event that will surely occur is _________. These events are called _________.

(iv) The total probability of all the elementary events of an experiment is __________.

(v) The probability of an event P(E) is greater than or equal to and less than or equal to __________.

Solution:

(i) The probability for any event E, P(E) + P(not E) = 1

(ii) The probability of an event that will never occur is 0. These events are called impossible events.

(iii) The probability of an event that will surely occur is 1. These events are called sure or certain events.

(iv) (iv) The total probability of all the elementary events of an experiment is 1.

(v) The probability of an event P(E) is greater than or equal to 0 and less than or equal to 1.
