To solve the problem, we need to identify the correct statement about the probability of an event \( P(E) \).
1. Understanding the Range of Probability:
The probability of any event always lies between 0 and 1, inclusive. That is:
\[
0 \leq P(E) \leq 1
\]
2. Evaluating the Given Options:
(1) \( P(E) = -1 \) → Incorrect (Probability can't be negative)
(2) \( P(E) \geq 1 \) → Incorrect (Probability can't be greater than 1)
(3) \( 0 \leq P(E) \leq 1 \) → Correct (This is the definition of probability)
(4) None → Incorrect (Option 3 is correct)
Final Answer:
The correct statement is \( 0 \leq P(E) \leq 1 \).
A shop selling electronic items sells smartphones of only three reputed companies A, B, and C because chances of their manufacturing a defective smartphone are only 5%, 4%, and 2% respectively. In his inventory, he has 25% smartphones from company A, 35% smartphones from company B, and 40% smartphones from company C.
