Answer: 16
Step-by-step explanation:
The number of outcomes exist , when a coin is flipped (tails , head) = 2
The number of possible outcomes , when 'n' number of coins are flipped :_
[tex]2^n[/tex]
For n= 4, the number of possible outcomes , when four coins are flipped :_
[tex]2^4=2\times2\times2\times2=16[/tex]
Hence, the possible outcomes exist when four fair coins are flipped = 16
