Question

If four coins are flipped in succession, then the number of possible outcomes is…………….

a. 8
b. 12
c. 16
d. 14

Answer 1

The easiest way to solve this problem is probably to just write down all the different possible outcomes of four consecutive tosses.
The possibilities are:
HHHH, HHHT, HHTH, HHTT,
HTHH, HTTH, HTHT, HTTT,
TTTT, TTTH, TTHT, TTHH,
THTT, THTH, THHT, THHH.
So we get 16 possible outcomes.

Answer: c. 16.
