Mean = it's really just another word for average. You add all the values up together, and divide the sum by the number of values there are. So here :
9 + 13 + 9 + 10 + 10 + 9 + 10 + 10 + 11 + 9 = 100
And now, you count how many values there are ^ up there. There are 10 values (just count how many numbers there are) and then you have to divide 100 by 10.
100 ÷ 10 = 10
Your MEAN is : 10
Given:
Gross income : 215
FICA tax : 29.33
Income tax : 29.33
State tax : 2%
City tax : 1%
Retirement fund : 3%
State tax = 215 * 2% = 4.30
City tax = 215 * 1% = 2.15
Retirement Fund: 215 * 3% = 6.45
Net Income = 215 - (15.16 + 29.33 + 4.30 + 2.15 + 6.45)
N.I. = 215 - 59.39
N.I = 157.61 Choice D.

Explicación paso a paso:
Dado que:
Número de sabor a refresco = 10
Número de sabor a piña = 1
Número de sabor a fresa = 1
P (primero es fresa) = número de sabor a fresa / número total de sabor
P (primero es fresa) = 1/10
P (el segundo es sabor a piña) = número de sabor a piña / número total de sabor
P (segundo sabor a piña) = 1/9
Probabilidades independientes:
P (primero es fresa) * P (segundo sabor a piña)
= (1/10) * (1/9)
= 1/90
= 0.011
