Option: A is the correct answer.

A.This could easily happen with a fair coin after only 5 flips.

Step-by-step explanation:

As we know that when a coin is tossed 5 times than the total number of outcomes that are resulting from these flips are:

2^5

where:

$2^5=2\times 2\times 2\times 2\times 2\\\\2^5=32$

Hence, the total outcomes that are possible are: 32

Also, when a coin is fair any of the possibility could come up:

All are tailsAll are heads.One tail four heads.One head four tail.Two tail three heads.Two heads three tails.

Hence, option: A is the correct answer.
