Answer:
[tex]Pr(Head) = \frac{2}{3}[/tex]
Step-by-step explanation:
The right parameters are:
[tex]Head = 12[/tex]
[tex]Toss = 18[/tex] (not 10)
Required
[tex]Pr(Head)[/tex]
The experimental probability of Head is:
[tex]Pr(Head) = \frac{Head}{Toss}[/tex]
This gives
[tex]Pr(Head) = \frac{12}{18}[/tex]
Simplify
[tex]Pr(Head) = \frac{2}{3}[/tex]
