1. Define theoretical probability.
2. What is the probability of each of the following?
a) picking the 9 of clubs from a deck of cards ? $$\displaystyle{\left\lbrace{\frac{{t}}{{i}}}{o}{n}\right\rbrace}$$
b) flipping heads with a coin ? $$\displaystyle{\left\lbrace{d}{e}{c}{i}{m}{a}{l}\right\rbrace}$$
c) picking a diamond from a deck of cards ? $$\displaystyle{\left\lbrace{p}{e}{r}{c}{e}{n}{t}\right\rbrace}$$
d) rolling a with 1 die ? $$\displaystyle{\left\lbrace{\frac{{t}}{{i}}}{o}{n}\right\rbrace}$$
e) rolling an even number with 1 die ? $$\displaystyle{\left\lbrace{d}{e}{c}{i}{m}{a}{l}\right\rbrace}$$
f) flipping heads for or tails with a coin ? $$\displaystyle{\left\lbrace{p}{e}{r}{c}{e}{n}{t}\right\rbrace}$$

Step 1
1. Theoretical probability is probability that is determined on the basis of reasoning.
2. a) picking the 9 of clubs from a deck of cards $$\displaystyle{\frac{{{1}}}{{{52}}}}{\left({\frac{{t}}{{i}}}{o}{n}\right)}$$
b) flipping heads with a coin $$\displaystyle{\frac{{{1}}}{{{2}}}}={0.5}{\left({d}{e}{c}{i}{m}{a}{l}\right)}$$
c) picking a diamond from a deck of cards choose 13 form 52. Which is $$\displaystyle{25}\%{\left({p}{e}{r}{c}{e}{n}{t}\right)}$$
d) rolling a 3 with 1 die $$\displaystyle{\frac{{{1}}}{{{6}}}}{\left({\frac{{t}}{{i}}}{o}{n}\right)}$$
e) rolling an even number with 1 die $$\displaystyle{\frac{{{3}}}{{{6}}}}={0.50}{\left({d}{e}{c}{i}{m}{a}{l}\right)}$$
f) flipping heads or tails with a coin $$\displaystyle{100}\%{\left({p}{e}{r}{c}{e}{n}{t}\right)}$$
Step 2
Experimental probability is probability that is determined on the basis of the results of an experiment repeated many times.
