Question

complete the expected value table.

x	p(x)	x*p(x)
0	0.2
1	0.2
2	0.4
3	0.2

a. 0 0.02 0.08 0.06
b. 0 0.2 0.8 0.6
c. 0.02 0.08 0.06

Explanation:

Step1: Calculate for \(x = 0\)

Multiply \(x\) and \(P(x)\): \(0\times0.2=0\)

Step2: Calculate for \(x = 1\)

Multiply \(x\) and \(P(x)\): \(1\times0.2 = 0.2\)

Step3: Calculate for \(x = 2\)

Multiply \(x\) and \(P(x)\): \(2\times0.4=0.8\)

Step4: Calculate for \(x = 3\)

Multiply \(x\) and \(P(x)\): \(3\times0.2 = 0.6\)

Answer:

\(x\)	\(P(x)\)	\(x\cdot P(x)\)
\(1\)	\(0.2\)	\(0.2\)
\(2\)	\(0.4\)	\(0.8\)
\(3\)	\(0.2\)	\(0.6\)
