When the occurrence of one event has no effect on the probability of the occurrence of another event, the events are called:
a) Independent.
b) Dependent
c) Mutually exclusive
d) Equally likely
Ans: a) Independent
Explanation:
a) If effect of one event doesn't affect the effect of another event then they are known as independent.
b) Since the effect of one event doesn't affect the effect of another event . Which shows that, both the event are not dependent.
c) 2 events said to be mutually exclusive events when they cannot both occur at the same time. Since events are occur at same time so it not mutually exclusive.
d) equally likely is not possible because in equally likely we assume that both the distribution are same so the amount of change in probability of one event will be same for the another event.
Therefore option 'a' is the correct answer
