3. Kobe likes to play basketball. Assume that
Kobe’s free throw attempts are BT with
p
=
0
.
85
.
(a) Kobe will shoot three free throws.
Calculate the probability that he ob
tains S, F, S, in that order.
(b) Kobe will shoot four free throws. Cal
culate the probability that he obtains a
total of exactly three successes.
(c) Next week Kobe will shoot two free
throws on Friday.
The number of
free throws he shoots on Saturday will
equal the number that he makes on
Friday.
