A coin is tossed 5 times. Find the probability that none are heads. Find the probability that most 2 are heads, the probability that none are heads is?
5 out of 20???For there is only one combination of getting no heads and that is tails-tails so multiply that by 5 and you get 5 and there are a total of 4 combinations so you multiply that by 5 and you get 20. So the answer is 5 out of 20
