An unbiased coin is tossed four times. find the probability of the given event. (round your answer to four decimal places.)
the coin lands heads more than once.

Step-by-step explanation:

When determining the probability that a coin lands on the head more than once, it is first important to know that every time you flip the coin, it has a 50% chance to land head’s up and 50% chance to land tail’s up. The combinations you can get with 4 flips are , HHHT, HHTH, HHTT, HTHH, HTHT, HTTH, H, THHH, THHT, THTH, THTT, TTHH, TTHT, TTTH, . As you can see, there are 16 possible outcomes and 11 of them have head’s coming up more than once. The chances of head’s coming more than once with four tosses of a coin is 68.75% (11/16 times 100).
