Q.

What is the sample space when two coins are tossed (H stands for head and T stands for tail)?

1. HH, HT, TH, TT

2. HH, TT

3. HT, TH

4. TH, HT, TT

Q.

Three coins are tossed simultaneously 200 times with the following frequencies of different outcomes.

$$\begin{array}{ccccc}Outcomes& 3heads& 2heads& 1head& Nohead\\ Frequency& 23& 72& 77& 28\end{array}$$
