Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
A be the event that the person has 2 siblings.
B be the event that the person does not have a pet.
Since they are not independent events.
Because if P(A|B) = 0.18
in case if they are independent events then, P(A|B) = P(A).
But here P(A) = 0.4
So, they are not independent events.
Hence, Fourth option is correct.
One way is to just expand it by using binomial theorem
or to use pascal's triangle
ok so
to find the nth term of a binomial, (a-b). where the binomial is to the r power you do
n-1=k
rCk times

and rCk=

so
4th term
4-1=3
6 is exponent
6C3

=

=

=

the 4th term is
Answer:
160cm^2
Step-by-step explanation:
So the surface area is basicly the sum of all the areas of the rectangles in this prism.
So the formula can be written as
.
The w stands for width, the h stands for height, and the l stands for length.
5cm is the width, 10 cm is the length, and 2 cm is the height.
So inserting all those values for the variabls the formula now looks like this.
.
So 5*10 is <u><em>50</em></u>
2*10 is <u><em>20</em></u>
2*5 is <em><u>10</u></em>
So adding all that up we get 80.
Then multiplyong that by 2 we get 160cm^2.
