2. 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

Answer

Explanation:

Step1: Understand Probability

A 2% probability means the event occurs 2 times in 100 trials or 1 time in 50 trials (since ( \frac{2}{100}=\frac{1}{50} )).

Step2: Evaluate Options

  • Option A: 1 time in 50 trials matches ( \frac{1}{50} = 2% ).
  • Option B: 1 time in 100 trials is 1%, not 2%.
  • Option C: 1 time in 500 trials is 0.2%, not 2%.
  • Option D: A 2% probability means it can occur, so "never" is wrong.

Answer:

A. It will occur 1 times every 50 trials.
