A = event that the ball drawn from urn #1 is white
B = event that the ball drawn from urn #2 is white
P(A) = probability of event A
P(A) = (number of white in urn #1)/(number total in urn #1)
P(A) = 3/(3+6)
P(A) = 3/9
P(A) = 1/3
P(B) = probability of event B
P(B) = (number of white in urn #2)/(number total in urn #2)
P(B) = 3/(3+8)
P(B) = 3/11
Because A and B are independent events, we can multiply the probabilities
P(A and B) = P(A)*P(B)
P(A and B) = (1/3)*(3/11)
P(A and B) = (1*3)/(3*11)
P(A and B) = 1/11
Answer: Choice A) 1/11
As far as I can tell is just a Permutation.
Answer:
-6
Step-by-step explanation:
5+3x=x-7
-x -x
5+2x=-7
-5 -5
<u>2x</u>=<u>-12</u>
2 2
x=-6
Answer:
0
Step-by-step explanation: 6x^2-2x=0
= \sqrt{6x^2} -2x = \sqrt{0}
6x-2x = 0
4x=0
x=0/4
x=0
Step-by-step explanation:
We know that diagonals bisect each other and the mid point of diagonals are equal .
