In a class of 30 students there are 17 girls. two students are picked randomly to represent the class in the SRC. determine the
Alla [95]

Answer:

See below in bold,.

Step-by-step explanation:

There are 30-17 = 13 boys in the class.

a.  Prob(First is a boy ) = 13/30 and Prob( second is a boy = 12/29).

As these 2 events are independent:

Prob( 2 boys being picked) = 13/30 * 12/29 =  26/145 or 0.179 to the nearest thousandth.

b. By a similar method to a:

Prob ( 2 girls being picked) =  17/30 * 16/29 = 136/435 = 0.313 to the nearest thousandth.

c.  Prob (First student is a boy and second is a girl) =  13/30 * 17/29 = 221/870.

Prob ( first student is a girl and second is a boy)  = 17/30 * 13/29 = 221/870

These 2 events are not independent so they are added:

Prob( one of the students is a boy)  = 2 (221/870 =  221/435 = 0.508 to the nearest thousandth.

Simplify.<br> 3^2+ (9-8/2)
solmaris [256]

Hi there! Hopefully this helps!

-----------------------------------------------------------------------------------------------------------

Answer: 14.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we calculate <u>3 to the power of 2</u> and get 9.

|

\/

9 + 9 - \frac{8}{2} = 14.

Now we add<u> 9 + 9</u> to get 18.

18 - \frac{8}{2} = 14.

Then, we<u> divide 8 by 2</u> to get 4.

18 - 4 = 14.

Then we subtract<u> 4 from 18</u> to get.....You guessed it,<u> 14</u>!
