Jeff typically makes three out of nine attempted free throws. What's the average waiting-time for Jeff to make his first basket,

and what's the probability he'll make a basket on or before the very last attempt within his average waiting-time?

Exercise 12.1.1: Coin flips and events. About A coin is flipped four times. For each of the events described below, express the

butalik [34]

Answer:

a $Pr = 0.25$

b $Pr = 0.50$

c $Pr = 0.1875$

Step-by-step explanation:

Given

$n = 4$ --- number of times

$r = 2$ --- faces of a coin

First, is to determine the sample size.

This is calculated as:

$Size =r^n$

$Size =2^4$

$Size =16$

Solving (a): First and last slip is head

This event is represented as:

$E=\{HHHH, HHTH, HTHH, HTTH\}$

The probability is calculated as:

$Pr = \frac{n(E)}{Size}$

$Pr = \frac{4}{16}$

$Pr = 0.25$

b) At least 2 consecutive flips that is heads.

This event is represented as:

$E=\{HHHH,HHHT,HHTH,HHTT,THHH,THHT,HTHH,TTHH\}$

The probability is calculated as:

$Pr = \frac{n(E)}{Size}$

$Pr = \frac{8}{16}$

$Pr = 0.50$

c) First is tail and at least 2 consecutive flips is head.

This event is represented as:

$E=\{THHH,THHT,TTHH\}$

The probability is calculated as:

$Pr = \frac{n(E)}{Size}$

$Pr = \frac{3}{16}$

$Pr = 0.1875$
