Answer:
P(B) = 0.85
Step-by-step explanation:
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:
These events are independent.
This means that 
. So
So
I believe the answer would be 90.
Answer:
10 / 38
Step-by-step explanation:
Black socks = 9
White = 10
Total = 10 + 9 = 19
Choosibg without replacement :
P(white) = 10 / 19
Second pick:
P(black) = 9 / 18 = 1/ 2
P(white then black) = 10/19 * 1/2 = 10/38
Well I wanna was the day you got home and we got to
Answer:
Step-by-step explanation:
- <em>Opposite angles of the cyclic quadrilateral are supplementary.</em>
Angles P and R are opposite to each other, the arcs intercepted by these two angles make a full circle, which is 360° and converted to inscribed angles it makes 180°, since we know the inscribed angle is half the value of the intercepted arc.
Same applies to opposite angle pair of ∠O and ∠Q.
