Currently Samsung ships 21.9% of the organic light-emitting diode (OLED) displays in the world. Let S be the event that a randomly selected OLED display made by samsung. Find P(S).
(Round your answer to 3 decimal places.)

Find P(S’)
(Round your answer to 3 decimal places.)

Find odds in the favor of event S.
(Round your answer to 3 decimal places.)

Find odds against event S.
(Round your answer to 2 decimal places.)

Step-by-step explanation:

Find P(S): P(A) + P(A')= 1

A and A' together comprise the sample space, their probabilities sum 1

(Turn 21.9% into a decimal) P(S)= 0.219

Find P(S'): P(A')= 1-P(A)

The probability of the compliment of A is found by subtracting P(A) from 1.

1 -0.219= 0.781; P(S')= 0.781

Find odds in the favor of events S.

(Round 3 decimal places.)

P(A) / 1- P(A)

.219 /.781= .280

Find odds against event S.

(Round your answer to 2 decimal places)

1- P(A) / P(A)

0.781 / .219= 3.566 ROUNDED 3.57

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
