Ateacher asks her students to write down the number of hours studied, rounded to the nearest half hour. she compiles the results and develops the probability distribution below for a randomly selected student. what is the mean of the probability distribution? probability distribution hours studied: x probability: p(x) 0.5 0.07 1 0.2 1.5 0.46 2 0.2 2.5 0.07 0.20 0.46 0.85 1.50

The mean of given probability distribution is 1.50

Step-by-step explanation:

We are given the following information in the question:

Hours Studies(x):        0.5       1        1.5        2         2.5

  Probability P(x):        0.07     0.2      0.46     0.2      0.07

We have to find the mean of the above probability distribution.

Formula:

Putting the values, we get,

Thus, the mean of given probability distribution is 1.50
