What is the probability ofNOTgetting an apple.

Meaning,

No apple on first try.

No apple on second try.

No apple on third try.

....

Thus, the probability for each one respectively are,

(40)/(50)

(39)/(49)*

(38)/(48)

...

(33)/(43)

Thus,

(40*39*38*...*33)/(50*49*...*43)=(40P8)/(50P8)=.1432

This is the probability of not getting an apple.

Thus, the probability of getting an apple is,

1-.1432=.8568

*)Because you now have 1 less of each fruit after your chose the first one.
