Question

the probability that a fair coun tossed 10 times will lsndheads up on all ten tosses is 1 out of ?

Answer 1

The probabiliti tha a coun is heads is 1/2 so the probability that that happen 10 times in row we have to multiply the probabilities so:

$\begin{gathered} p=\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}\cdot\frac{1}{2}=\frac{1}{2^{10}} \\ p=\frac{1}{1024} \end{gathered}$
