Question

Who ever answers first gets the brainliest :)

Answer 1

Answer:

Step-by-step explanation:

one head is 1/2 tails twice is 1/4

multiply and get 1/8 but thats not the answer yet

a possibility could be htt or tht

so u muiltiply by number of possibilities of one head which 3!/2!

3/8

Answer 2

Answer:

$\frac{3}{8}$ is the probability of getting exactly one heads.

Step-by-step explanation:

Probability : It is defined as the extent to which an event is likely to occur. That means, it is measured by the ratio of the favorable outcomes to the total number of possible outcomes.

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of favorable outcomes}}$

We have : sample space = S =[HHH,HHT,HTH,HTT,THH,THT,TTH,TTT ]

Favorable outcomes of getting single head (H) = [HTT, THT, TTH]

Probability of getting single heads = P(H)

P(H) = $\frac{3}{8}$

$\frac{3}{8}$ is the probability of getting exactly one heads.
