Answer:
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
