Question

1. a probability of 2% means we can expect which of the following? it will occur 1 times every 50 trials. a it will occur 1 times every 100 trials. b it will occur 1 times every 500 trials. c it will never occur. d

Explanation:

Step1: Convert 2% to a fraction

2% can be written as $\frac{2}{100}=\frac{1}{50}$. This means that the probability of the event occurring is 1 out of 50 trials on average.

Step2: Analyze each option

• Option A: If the probability is $\frac{1}{50}$, it means on average the event will occur 1 time every 50 trials.
• Option B: $\frac{1}{100}$ is 1%, not 2%, so this is incorrect.
• Option C: $\frac{1}{500}$ is 0.2%, not 2%, so this is incorrect.
• Option D: A probability of 2% means the event can occur, so "never occur" is wrong.

Answer:

A. It will occur 1 times every 50 trials.
