Fill in the P(X=x) values to give a legitimate probability distribution for the discrete random variable , whose possible values
Naddika [18.5K]

For a probability distribution to be represented, it is needed that P(X = 0) + P(X = 1) = 0.44. Hence one possible example is:

  • P(X = 0) = 0.40.
  • P(X = 1) = 0.04.

<h3>What is needed for a discrete random variable to represent a probability distribution?</h3>

The sum of all the probabilities must be of 1, hence:

P(X = 0) + P(X = 1) + P(X = 3) + P(X = 4) + P(X = 5) = 1.

Then, considering the table:

P(X = 0) + P(X = 1) + 0.15 + 0.17 + 0.24 = 1

P(X = 0) + P(X = 1) + 0.56 = 1

P(X = 0) + P(X = 1) = 0.44.

Hence one possible example is:

  • P(X = 0) = 0.40.
  • P(X = 1) = 0.04.

natima [27]

Answer: 7 7/8 hours long

Step-by-step explanation:

April worked 1 1/2 times as long as Carl did. 1 1/2 can be rewritten as 3/2. Number of Hours April worked on math project 3/2 times the Number of Hours Carl worked on Math project. Which Carl worked 5 1/4 hours long, which can be rewritten as 21/4

Which description best fits the distribution of the data shown in the histogram?
Sedaia [141]

Option B: Approximately bell-shaped

Explanation:

Option A: Skewed

A histogram is said to be skewed if most of the larger values falls either on the left or right side.

Clearly, the given histogram is not skewed.

Thus, Option A is not the correct answer.

Option B: Approximately bell-shaped

A graph is said to be bell shaped if a vertical line is drawn at the center which will form a mirror image of the left half of the graph with the right half.

Clearly, the given histogram is approximately bell-shaped.

Thus, Option B is the correct answer.

Option C: Uniform

A graph is said to be uniform if its data is equally spread across the range.

Clearly, the given histogram is not Uniform.

Thus, Option C is not the correct answer.

Option D: Skewed left

A graph is said to be skewed left if the smaller values fall on the left side of the graph.

Clearly, the given histogram is not skewed left.

Thus, Option D is not the correct answer.

Hence, Option B is the correct answer.
