Answer:
P(A) = 44.44%
P(B) = 50%
P(B|A) = 37.5%
P(B|A) different from P(B).
A and B are independent.
Step-by-step explanation:
If we have a total of 180 students, and 80 of them have a Playstation, we have that P(A) = 80/180 = 0.4444 = 44.44%
If we have 90 students that have a Xbox, we have that P(B) = 90/180 = 0.5 = 50%
If we have 30 students that have both consoles, we have that P(A and B) = 30/180 = 0.1667 = 16.67%
To find P(B|A), we will find for a student that has an Xbox inside the group of students that has a Playstation, that is, we have 30 students in a total of 80 students, so P(B|A) = 30/80 = 0.375 = 37.5%
P(B|A) is different from P(B), the first is 37.5% and the second is 50%, so events A and B are independent events.
To find the volume, multiply length, width, and height together
19 x 20.4 x 6 = 2325.6
2325.6 in³ is your answer
hope this helps
First simplify the radical then simplify the fraction then get the root iut of the denominator, you should get the second one

Answer:
C. 1/25
Step-by-step explanation:
I assume this is a fair spinner and the probability of landing in all colors is equal.
First spin:
p(purple) = 1/5
Second spin:
p(purple) = 1/5
The two spins are independent events, so the probability of landing on purple twice is the product of the two individual probabilities.
p(purple and purple) = 1/5 * 1/5 = 1/25
