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.
You will need to multiply 2.25 by 375.5 which will then give you 844.87 but if we round it the answer will be 844.9
