Chapter 14.2, Problem 1E

The set of all possible outcomes of an experiment is called the ____________ _____________. A subset of the sample space is called an ____________. The sample space for the experiment of tossing two coins is $S=\left\{HH,\underset{\_}{},\underset{\_}{},\underset{\_}{}\right\}$. The event “getting at least one head” is $E=\left\{HH,\underset{\_}{},\underset{\_}{}\right\}$. The probability of getting at least one head is $P\left(E\right)=\frac{n\left(\underset{\_}{}\right)}{n\left(\underset{\_}{}\right)}=\underset{\_}{}$.
