Question 1197903
p = 24.8% / 100 = .248
q = 1 - .248 = .752
p is the proportion of light emitting diodes that are shipped by samsung.
q is the proportion of light emitting diodes that are not shipped by samsung.
q is equal to 1 - p
p(s) is the probability that a randomly selected oled display was shipped by samsung.
p(not s) is the probability that a randomly selected oled display was not shipped by samsung.
odds in favor = p(s) / p(not s) = .248 / .752
odds against = p(not s) / p(s) = .752 / .248
p(s) = p(s) / ((p(s) + p(not s)) = .248 / (.248 + .752) = .248 / 1 = .248
p(not s) = p(not s) / (p(s) + p(not s) = .752 / (.248 + .752) = .752 / 1 = .752


p(not s) is the same as p(s')


here's a reference on probability and odds.
