Answer:
P(S) = 0.219.
P(S') = 0.781.
The odds in favor of event S = 0.281.
The odds against event S = 3.57.
21.9% of the organic light-emitting diode (OLED) displays in the world are made by Samsung, hence:
P(S) is the probability of a chip being made by Samsung, hence P(S) = 0.219.
P(S') is the probability of a chip not being made by Samsung, hence P(S') = 1 - 0.219 = 0.781.
The odds in favor of an event with probability p is given by:
(p)/(1 - p)
Hence, the odds in favor of event S =
(0.219)/(0.781) = 0.28
so the odds against event S are:
(0.781)/(0.219) = 3.57
