If event a and event b cannot occur at the same time then a and b are said to be?

Solution:

Given the condition that event A and event B cannot occur at the same time.

By the definition,

if two events A and B cannot occur at the same time, then they are called mutually exclusive events or disjoint events.

For example,

while tossing a fair coin, we get either head or tail but not both at the same time.

While rolling a die, the probability of getting the number 6 or 5

= 1/6 + 1/6

= 1/3.

Hence, they are called mutually exclusive or disjoint sets.

If event a and event b cannot occur at the same time then a and b are said to be?

Summary:

If event a and event b cannot occur at the same time then a and b are said to be mutually exclusive events or disjoint sets.
