Question

In an experiment, a number cube is rolled 4 times. The number of times a 5 shows is recorded. Sixty trials of the experiment are run.

The table shows the frequency of any number of 5s occurring in the trials.

Number of 5s 0 1 2 3 4
Frequency 6 9 33 9 3
Create a probability distribution for the discrete variable.

Drag the sliders on the horizontal axis to represent the probability distribution.

Answer 1

Explanation:

Given that in an experiment, a number cube is rolled 4 times. The number of times a 5 shows is recorded. Sixty trials of the experiment are run.

No of 5's Freq Prob

0 6 0.1

1 9 0.15

0 33 0.55

3 3 0.05

4 9 0.15

60 1

The above is the probability distribution of the discrete variable.
