Answer:
a) It is probability distribution
b) mean = 2.5
c) Standard Deviation = 1.11
Step-by-step explanation:
We are given the following in the question:
x 0 1 2 3 4 5
P(x) 0.033 0.149 0.318 0.318 0.149 0.033
Probability distribution:
Since, the summation of all the probabilities is 1 and each value of probability is between 0 and 1, the given is a probability distribution.
Mean of probability distribution:
Thus, the mean of distribution is 2.5
Standard deviation of probability distribution:
Thus, the standard deviation of the probability distribution is 1.11
