Afair coin is flipped 4 times. what is the probability that at least two heads are flipped?

60% chance or 3/5 probability

Here are the different probabilities by flipping the coin 4 times. H=heads T=tails

              HHHT                HHTT                  HTTT                    

1/5                          1/5                  1/5                     not 1/5                  not 1/5

If there are 2 or more heads in one of these pairs that pair is 1/5 of the total pairs.

3/5 probability that there will be 2 or more heads flipped, or 60%

P.S- it is also a 3/5 chance for 2 or more tails to be flipped also.

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
