Answer 1

x	f(x)	xP(x)	x2P(x)
0	0.021	0.000	0.000
1	0.121	0.121	0.121
2	0.284	0.568	1.135
3	0.333	1.000	2.999
4	0.196	0.782	3.130
5	0.046	0.230	1.148
	total	2.700	8.532
	E(x) =μ=	ΣxP(x) =	2.7000
	E(x2) =	Σx2P(x) =	8.5320
	Var(x)=σ2 =	E(x2)-(E(x))2=	1.2420
	std deviation=	σ= √σ2 =	1.1145

from above mean μ =2.700

and std deviation σ=1.1
