Probability of mutually exclusive events

Example: rolling dice once and getting 6 and 2

Example: Arif throws a biased coin. The probability of getting tails is 0.7. Therefore, the probability of getting heads is 1-0.7=0.3

When two events CANNOT happen at the same time, the events are said to be MUTUALLY EXCLUSIVE.

​

An example of this is getting heads on a coin and a tail on the same coin in the same toss.

​

Another example would be getting a six on a regular die and a five on the same die in the same roll.

​

A pre-Covid example would be being at school and being at home at the same time.

Example: Arif throws a biased coin. The probability of getting tails is 0.7. Therefore, the probability of getting heads is 1 - 0.7 = 0.3
