Question

A set of cards contains cards numbered 1 – 8. Mrs. Jacob’s class is conducting an experiment in which a card is drawn from the pile, the number is recorded, and then the card is returned to the set. The class will conduct 1,000 trials. Based on the theoretical probability, which is the best prediction for the number of times a 4 will be drawn from the pile?

111
125
143
250

Answer 1

i think that your anwser is 125

Answer 2

2nd Option is correct.

Explanation:

We are given a set of cards containing numbers from 1 to 8 on each cards.

Randomly a card is drawn and noted.

This is repeated 1000 times.

To find: Number of time 4 will be drawn from the pack using theoretical probability.

We know that,

Theoretical Probability: Probability which is based on reasoning and written as a ratio of the number of favorable outcomes to the total number of outcomes.

Probability of getting 4 from the pack =
`(1)/(8)`

Now, Number of the times 4 will be drawn from pack out of 1000 times

=
`(1)/(4)*1000`

= 125

Therefore, 2nd Option is correct.
