Given that A coin is flipped 5 times and we need to find how many distinct outcomes are possible if the last flip must be heads?

In each toss we have two choices -> Heads or Tails

For each of the first four outcomes we have 2 choices each => 2 * 2 * 2 * 2 = 16 ways

For the fifth toss we have only one choice as we are getting Heads

=> Total choices = 16 * 1 = 16

So, Answer will be E
Hope it helps!
