Answer:
a= 1/2 and b= 1/2
Step-by-step explanation:
The given probability can be expressed in the form of binomial expansion where a= p and b= q
Therefore a= 1/2 and b= 1/2
For n= 8 trials the binomial expansion can be written as
[ p+q] ^n = [ 1/2+1/2]^8
=(1/2)^0(1/2)^8 +8C1(1/2)^7(1/2)+8C2(1/2)^6(1/2)^2+8C3(1/2)^5(1/2)^3+8C4(1/2)^4(1/2)^4+8C5(1/2)^3(1/2)^5+8C6(1/2)^2(1/2)^6+8C7(1/2)(1/2)^7+8C8(1/2)^0(1/2)^8
=
1(1/2)^0(1/2)^8 +8(1/2)^7(1/2)+28(1/2)^6(1/2)^2+56(1/2)^5(1/2)^3+70(1/2)^4(1/2)^4+56(1/2)^3(1/2)^5+28(1/2)^2(1/2)^6+8(1/2)(1/2)^7+1(1/2)^0(1/2)^8
=
1/(2)⁸ { 1+ 8+28+56+70+56+28+8+1}
= 1/(2)⁸ {256}
= 1
The total probability is always 1.
Also P+q= 1
1/2+1/2= 1
Step-by-step explanation:
the area of a parallelogram is
baseline × height
which is in our case
9 × 7 = 63 m²
The correct answer of the given question above would be option D. The thing that must happen for historians to consider a particular time in a civilization as a classical period is that, the civilization must make extraordinary achievements in areas such as art and science.
-8y = -2x + 16
y = 1/4x - 2
y = 1/4x + 3
You would convert the fractions into decimals 2 1/4 (2.25) and 18 1/2 (18.5) Then you would do 18.5 Divided by 2.25 which equals 8.2 then convert 8.2 to a fraction 8 1/5 so the answer is 8
