A tree diagram. The outcomes are (h, h, h), (h, h, t), (h, t, h), (h, t, t), (t, h, h), (t, h, t), (t, t, h), (t, t, t).
This tree diagram shows all the possible outcomes for tossing a coin three times.

How many possible outcomes are there when a coin is tossed 3 times?

How many outcomes include exactly one tail?

Number of possible outcomes when a coin is tossed 3 times = 8

Number of outcomes which include exactly one tail = 3

Explanation:

Given: When a coin is tossed three times, the outcomes are (h, h, h), (h, h, t), (h, t, h), (h, t, t), (t, h, h), (t, h, t), (t, t, h), (t, t, t)

To find: number of possible outcomes when a coin is tossed 3 times

number of outcomes which include one tail

Solution:

An outcome is a result of an experiment. An event can have more than one possible outcome.

Number of possible outcomes when a coin is tossed 3 times = 8

Outcomes that include exactly one tail are (h, h, t), (h, t, h), (t, h, h).

Number of outcomes which include exactly one tail = 3

the aksumite empire was an ancient kingdom located in what is now northern ethiopia from the period of 100 ad to 940 ad. its capital was the city of aksum. the kingdom established itself as one of the 4 great powers at its time, along with persia, rome, and china.

the kingdom was rich in goods like gold, iron, and salt. it established strong commercial ties with the regions governed by rome, egypt, and persia (arabia). aksum was a key location in this commercial network. trade was also facilitated with the introduction of the aksumite currency.
