Solution:
The Required Rule for the above Table is
For first case
Put x = 6 in the rule we get
as shown in the table
For second case
Put x = 7 in the rule we get
as shown in the table
For third case
Put x = 8 in the rule we get
as shown in the table
For fourth case
Put x = 9 in the rule we get
as shown in the table
For fifth case
Put x = 10 in the rule we get
as shown in the table

Answer:
μ ≈ 2.33
σ ≈ 1.25
Step-by-step explanation:
Each person has equal probability of ⅓.
The mean is the expected value:
μ = E(X) = ∑ X P(X)
μ = (1) (⅓) + (2) (⅓) + (4) (⅓)
μ = ⁷/₃
The standard deviation is:
σ² = ∑ (X−μ)² P(X)
σ² = (1 − ⁷/₃)² (⅓) + (2 − ⁷/₃)² (⅓) + (4 − ⁷/₃)² (⅓)
σ² = ¹⁴/₉
σ ≈ 1.25
