Disks of polycarbonate plastic from a supplier are analyzed for scratch and shock

The values are given as

P(A)=0.67

P(B)=0.66

P(A')=0.33

P(A∩B)=0.55

P(AUB)=0.78

P(A'UB)=0.88

Step-by-step explanation:

As from the given data

                                  | Shock Resistance

                                  |   High      |   Low    | Total

Scratch           | High |     71         |    14       |   85

Resistance     | Low  |     16         |   28       |   44

Total                          |     87        |   42       |   129

As A=High Shock Resistance  and B=High Scratch Resistance thus the values are calculated as

P(A)=87/129=0.67

P(B)=85/129=0.66

P(A')=1-P(A)=1-0.67=0.33

P(A∩B)=71/129=0.55

P(AUB)=P(A)+P(B)-P(A∩B)=0.67+0.66-0.55=0.78

P(A'UB)=P(A')+P(B)-P(A'∩B)=(42/129)+0.66-(14/129)=0.88

Hello There!

1.4 as a fraction is 1

STEP 1: You want to rewrite the decimal number that you're converting to a fraction with a denominator of 1. In this case, the fraction would be

STEP 2: You want to multiply to remove one decimal place.

x =

STEP 3: You want to simplify the improper fraction of 7/5 because it's reduced and our mixed number fraction will be 1

1.4 as a percent is 140%

An easy way to make a decimal to a percent is to move the decimal point two spaces to the right and then you want to add the % sign at the end.

1.4 becomes 140%
