Question

Suppose you toss a fair coin six times. What is the probability of all the six tosses resulting in heads

Answer 1

The probability of getting all heads is 1 / 2^6 = 1/64 as there is only 1 event where this happens in a possible 2^6 = 64 events. It is the same as the probability of getting all tails. The probability of getting at least 1 head is 1 - p(all tails) = 63/64.

Answer 2

3/6

Explanation:

Every time you flip its a 1/2 chance (theres 2 sides on a coin), so if you flip it 6 times(divide 6 by 2) its probable 3 of those flips will be heads
