Question

Clark tosses a coin two times. Find the probability of heads followed by heads.A) 1/2B) 1/3C) 1/4D) 1/8

Answer 1

Probability is define as:

`P(A)=\frac{Number\text{ of favorable outcome }}{Total\text{ number of outcome}}`

If coin tosses two times then favorable outcome that mean heads chance is =2

total outcome is =4

so probability is:

`\begin{gathered} P(A)=(2)/(4) \\ =(1)/(2) \end{gathered}`
