1 F(-∞) is always equal to Zero One Two Negative one
2 When sample space S is partitioned into some mutually exclusive events such that their union is sample space itself. Then the events are called Simple events Compound events Equally likely events Exhaustive events
3 Probability of an event cannot be Negative Positive Zero One
4 A set containing only one element is called Null set Universal set Subset Singleton set
5 If an event consist of more than one sample point it is called Simple event Compound event Exhaustive event Likely event
6 If two events cannot occur together they are said to be Independent events Dependent events Mutually exclusive events Equally likely events
7 If the chance of occurance of two events are same then such events are called Independent events Dependent events Mutually exclusive events Equally likely events
8 If the occurance of one event is not effected by the occurance of other than these events are called Dependent Independent Simple Compound events
9 Subset of sample space is called Event Simple event Compound event Experiment
10 An experiment which produced different outcomes even if it is repeated a large number of times, under similar conditions is called Event Compound event Random experiment None of these
11 A set representing all possible out comes of a random experiment is called Sample space Universal set Simple event Random experiment
12 Two events A and B are mutually exclusive if P(A∪B) = P(A) - P(B) P(A) + P(B) P(A)P(B) - P(A<span style="color: rgb(0, 0, 0); font-family: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif; font-size: 18px; line-height: 23.390625px;">∪</span>B) P(A) + P(B) - P(A<span style="color: rgb(0, 0, 0); font-family: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif; font-size: 18px; line-height: 23.390625px;">∪</span>B)
