Question 14

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
