Currently Samsung ships 20.9 percent of the organic light-emitting diode (OLED) displays in the world. Let $S$ be the event that a randomly selected OLED display was made by Samsung.
(a) Find $P(S)$. (Round your answer to 3 decimal places.)
(b) Find $P(S)$. (Round your answer to 3 decimal places.)
$P(S) \quad 1 \quad \square$
Answer
Final Answer: $P(S) = \boxed{0.209}$
Step 1 ：Let $S$ be the event that a randomly selected OLED display was made by Samsung.
Step 2 ：Currently Samsung ships 20.9 percent of the OLED displays in the world.
Step 3 ：The question is asking for the probability that a randomly selected OLED display was made by Samsung.
Step 4 ：This is given by the percentage of OLED displays that Samsung ships, which is 20.9 percent.
Step 5 ：To convert this percentage to a probability, we divide by 100.
Step 6 ：So, $P(S) = \frac{20.9}{100} = 0.209$
Step 7 ：Final Answer: $P(S) = \boxed{0.209}$
