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
WARRIOR [948]

Using the probability concept, the distribution is given as follows:

  • P(X = 0) = 0.1.
  • P(X = 1) = 0.15.
  • P(X = 2) = 0.55.
  • P(X = 3) = 0.15.
  • P(X = 4) = 0.05.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The distribution gives the <u>probability of each outcome</u>.

In this problem, there were 60 trials, hence the distribution is given as follows:

  • P(X = 0) = 6/60 = 1/10 = 0.1.
  • P(X = 1) = 9/60 = 3/20 = 0.15.
  • P(X = 2) = 33/60 = 11/20 = 0.55.
  • P(X = 3) = 9/60 = 3/20 = 0.15.
  • P(X = 4) = 3/60 = 1/20 = 0.05.
