Question

What is the probability of getting two heads and one tail when a coin is flipped three times? 1/3 3/8 1/2

Answer 1

Referring to the table attached, there is 3 possible outcomes between the total eight possibilities that we got two HEADs and one Tail if a coin is flipped three times.


`P= (number ~of ~possible~outcomes~of~2H+1T)/(total) = (3)/(8)`

Answer 2

`\text{The probability is }(3)/(8)`

Explanation:

Given that a coin is flipped three times.

we have to find probability of getting two heads and one tail.

Total outcomes are

`S=\{HHH, HHT, HTH, THH, TTT, TTH, THT, HTT\}`

Total number of outcomes=8

Favourable outcomes are HHT, HTH, THH

Number of favourable outcomes=3

`Probability=\frac{\text{No. of Favourable outcomes}}{\text{Total number of outcomes}}=(3)/(8)`

`\text{Hence, the probability is }(3)/(8)`
