Step-by-step explanation:
Answer:
0.3333 = 33.33% probability that this red ball is from box A.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is

In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Red ball
Event B: From box A.
Probability of a red ball:
3/10 = 0.3 of 1/2 = 0.5(box A)
6/10 = 0.6 of 1/2 = 0.5(box B). So

Probability of a red ball from box A:
0.3 of 0.5, so:

What is the probability that this red ball is from box A?

0.3333 = 33.33% probability that this red ball is from box A.
Your multiplying 2 on the 4,8,16,32 one then adding 1 on the 1,2,3 one which could determine the rate of change
Answer:
-7
Step-by-step explanation:
You use the quadratic formula of
to get:
a = 1
b = 7
c = -13
then you plug that into x= (-b ± √b²-4ac)/(2a) :
x= ( -7 ± √7²- 4(1)(-13) )/(2(1))

The sum of these two x values turns out to be:
