Multiple choice

A die is tossed $80$ times and the number $3$ is obtained $14$ times. Now, a dice is tossed at random, then the probability of getting the number $3$ is ________.

  1. $\dfrac {7}{40}$
  2. $\dfrac {3}{14}$
  3. $\dfrac {1}{2}$
  4. $\dfrac {3}{40}$

A Correct answer
Explanation

The experimental probability from 80 tosses is 14/80 = 7/40. The question asks for the probability of getting 3 when a die is tossed at random, which is a theoretical probability of 1/6. Given the options, the question likely expects the experimental probability derived from the provided data.

AI explanation

The empirical probability formula is the number of times an event occurs divided by the total number of trials. Here, the number 3 is obtained 14 times out of 80 total tosses. Therefore, the required probability is 14 divided by 80. The result is 7/40.
