A flipped coin coming up heads and the same coin coming up tails at the same time is impossible so they are mutually exclusive events. If you roll a sixsided die, each of the sides 1, 2, 3, 4, 5, 6 are mutually exclusive because only one side can be on top at once.
Pam Kalyssa, Here's anothe example. Roll two dice. One event is that each of the numbers that come up is even. The second event is that the sum of the numbers that come up is odd. These are mutually exclusive events because if the two numbers are even so is their sum. Penny Hi Kalyssa. Mutually exclusive just means exactly one of the choices is true. For example, if I am sleeping, then I am not awake. If I am not sleeping, then I am awake. Another example might be this: If I go swimming with my friends at the beach this afternoon, I cannot also spend the afternoon at my sister's birthday party. But if I go to the party, I can't go swimming as well. They are mutually exclusive. Stephen La Rocque.>
