Tossing a single coin can have two possible outcomes, which are heads and tails. We have 6 coins present in this case. To solve for the number of possible outcomes, we have
[tex]P=2^n[/tex]Solving for the number of outcomes, we get
[tex]P=2^6=64[/tex]Hence, we have 64 possible outcomes when tossing 6 coins at once.
Answer: C. 64
