Question. 14
An event is very unlikely to happen. Its probability is closest to
(A)
0.0001
(B)
0.001
(C)
0.01
(D)
0.1
Detailed Answer with Explanation:
Step 1: Probability of an event is always between 0 and 1.
Step 2: If the probability is close to 0, the event is very unlikely (almost impossible).
Step 3: Compare the given numbers:
- 0.0001 = one in ten thousand chance (extremely small).
- 0.001 = one in a thousand chance (still small, but bigger than 0.0001).
- 0.01 = one in a hundred chance (more likely than above).
- 0.1 = one in ten chance (not “very unlikely,” actually fairly possible).
Step 4: Out of the options, 0.0001 is the smallest and therefore shows the “very unlikely” situation.
Final Answer: Option (A) 0.0001
