Answer 6

If 1 coin is tossed there would be 2 possible outcomes, (Head or Tail).
Notice that the number of ways is 2 or 21.

If 2 coins are tossed there are 2 possible outcomes for the 1st coin.
Then for each of those 2 possible outcomes for the 1st coin, there are
2 possible otcomes for the 2nd coin. That's 2·2 or 4 ways. Notice that
the number of ways for 2 coins is 2·2 or 22.

If 3 coins are tossed there are 2 possible outcomes for the 1st coin.
Then for each of those 2 possible outcomes for the 1st coin, there are
2 possible otcomes for the 2nd coin. That's 2·2 or 4 ways for the first
two coins. Then for each of those 4 possible outcomes for the 1st coin,
there are 2 possible otcomes for the 3rd coin. That's 2·2·2 or 4·2 or
8 ways for the three coins. Notice that the number of ways for 3 coins
is 2·2·2 or 23.
