Mathematics Question on permutations and combinations
A coin is tossed 3 times and the outcomes are recorded. How many possible outcomes are there?
Answer
When a coin is tossed once, the number of outcomes is 2 (Head and tail) i.e., in each throw, the number of ways of showing a different face is 2.
Thus, by multiplication principle, the required number of possible outcomes is 2 x 2 x 2 = 8
