katovenus [111]

Answer: The required probability is 0.3296.

Step-by-step explanation:

Since we have given that

Number of songs = 105

Number of songs are by the Beatles = 10

So, Number of songs are not by the Beatles = 105-10=95

So, the probability that the first Beatles song heard is the fifth song played is given by

\dfrac{^{95}C_4\times ^{10}C_1}{^{105}C_5}\\\\=0.3296

Hence, the required probability is 0.3296.

Juliette works at a local law firm, Law Offices of Dane Gray, and attends school in the evenings at Reno Community College (RCC). She is taking some general classes and is not sure what degree she wants to pursue yet. She is taking three units this semester. Full-time status at RCC is nine units. Juliette’s mother watches Sabrina after school and in the evenings (no charge) so that Juliette can work and take classes at RCC. Social security numbers are 412-34-5670 for Juliette and 412-34-5672 for Sabrina. Their birth dates are as follows: Juliette, 10/31/1988; and Sabrina, 3/1/2013.

Wages (box 1) = $ 29,502.30

Federal W/H (box 2) = $ 1,007.14

Social security wages (box 3) = $ 29,502.30

Social security W/H (box 4) = $ 1,829.14

Do not skip rows, while entering in Dependents section of Form 1040 PG1.)

 

Use the appropriate Tax Tables and EIC table.

P = 40(h) - expenses

h = 200

Expenses = 4000,325,375

P = 40(200) - (4000+325+375)

P = 8000 - 4700
