B) The probability that both marbles are purple is 2.22%.
C) The probability that you pick at least one purple marble is 98%.
<h3><u>Probability</u></h3>
The question is incomplete, since the number of marbles of each color in the bag is missing: 3 blue, 5 green, and 2 purple marbles.
Now, to answer the questions, the following calculations must be done:
- B) 2/10 x 1/9 = X
- 0.2 x 0.11111 = X
- 0.022222 = X
- X x 100 = 2.22
- C) 100 - (2/9x9) = X
- 100 - 2 = X
- 98 = X

Answer:
The answer is option A.
∆BDC is a right angled triangle
Angles in a triangle add up to 180°
That's
z + 35 + 90 = 180°
z = 180 - 35 - 90
z = 55°
Alternate angles are equal
Angle DBC = Angle BDA
That's
35 = 7y
Divide both sides by 7
y = 5
y = 5 z = 55
Hope this helps you
4X213= 852 and you just put it like this 800+50+2
18 = ab^2
60.75 = ab^5
from first equation:- a = 18/b^2
so
60.75 = (18/b^2) * b^5
60.75 = 18b^3
b = cube root (60.75 / 18)
b = 1.5
so a = 18/1.5^2 = 8
so the required equation is y = 8(1.5)^x
