Tim can select 4 of his classes from the following options: 1) algebra, 2) American Sign Language,
3) typing, 4) English, 5) Spanish, 6) tennis, and 7) science.

There are four classes to be chosen out of those given seven classes.

ruchi,

you want four distinct (*specific*) items chosen among seven distinct items without replacement.


One of the interpretations:

\(\displaystyle Prob. \ of \ \frac{1}{7} \ for\ the \ first \ item \ times\)

\(\displaystyle prob. \ of \ \frac{1}{6} \ for \ the \ second \ item \ times\)

\(\displaystyle prob. \ of \ \frac{1}{5}\ \ for \ the \ third \ item \ times\)

\(\displaystyle prob.\ of \ \frac{1}{4} \ for \ the \ fourth \ item\)


And continue . . .
