Answer: False.
Step-by-step explanation:
The probability for any event = [tex]\dfrac{\text{favorable outcomes}}{\text{Total outcomes}}[/tex]
Definition : A simple event is an event that has only one possible favorable outcomes.
If we toss a coin and roll a die .
The possible outcomes for event "tossing tails and rolling a 4 or 6" = {(T, 4) , (T,6)}
Since this event has 2 possible favorable outcomes , Therefore it is not an simple event.
Hence, the given statement is "false".
