### Instruction: help me answer this question Describe three events which are mutually exclusive and exhaustive., think step by step
### Assistant:  , The answer is Let P be the event of getting exactly two tails. So, P = (HTT, TTH, THT). Let Q be the event of getting at least two heads. So, Q = (HHT, HTH, THH, HHH). Let R be the event of getting only one tail. So, C= (TTT). Therefore, P, Q, and R are mutually exclusive and exhaustive.
