Consider there are 2 bits. Find out the total combinations of 0 and 1 to fill the two bits. They are 00, 01, 10, 11 = 2^2

For 3 bits = 000, 001, 010, 100, 111, 110, 100, 101 = 2^3

I general, there are 2 possible oucomes for each bit. So the total possible outcomes for 32 bits = 2^32. Same as total combination of results possible for a fair coin tossed 32 times.
