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:

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

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

$Pr = 0.1875$

Answer:

x=75°and y=x= 75°

Step-by-step explanation:

Reason: opposite angles are equal and how I got 75 is by drawing an extension line and finding the other angle (i.e. angle on a straight line=180) so 180-105=75.

Can Someone Simplify this <br> 2 ( 3 X - 4 ) + ( X + 11 ) + 5

alexandr402 [8]

First, distribute 2 through the parentheses.
Then, take out the parentheses of (x+11)

6x-8+x+11+5

Now collect the like terms.

6x+x=7x
-8+11+5=+8

So the answer is: 7x+8
