Question

Determine whether a probability distribution is given. If a probability distribution is given, find its mean. (Round to the nearest thousandth). If a probability distribution is not given, state (not a probability distribution). (Check your spelling!)

x	P(x)
1	0.001
2	0.020
3	0.105
4	0.233
5	0.242

Answer 1

x	1	2	3	4	5
P(x)	0.001	0.020	0.105	0.233	0.242

to be a probability distribution sum of all probabilities should be 1 and it should be 0 P(x) 1

here, 0.001+0.020+0.105+0.233+0.242=0.601 1

hence we are not given a probability distribution.

however if the probabilities add to 1 then MEAN=
