Answer:
P(B|A)=0.25 , P(A|B) =0.5
Step-by-step explanation:
The question provides the following data:
P(A)= 0.8
P(B)= 0.4
P(A∩B) = 0.2
Since the question does not mention which of the conditional probabilities need to be found out, I will show the working to calculate both of them.
To calculate the probability that event B will occur given that A has already occurred (P(B|A) is read as the probability of event B given A) can be calculated as:
P(B|A) = P(A∩B)/P(A)
= (0.2) / (0.8)
P(B|A)=0.25
To calculate the probability that event A will occur given that B has already occurred (P(A|B) is read as the probability of event A given B) can be calculated as:
P(A|B) = P(A∩B)/P(B)
= (0.2)/(0.4)
P(A|B) =0.5
Answer:
80
Step-by-step explanation:
There are four 4 by 3 rectangles, so I did 4x3 and got 12, then multiplied by 4 to get 48. There are also two 4 by 4 squares, so 4x4=16 and 16x2=32
32+48=80

Answer:
x=7, y=16
Step-by-step explanation:
2x+5=x+12
2x=x+7
x=7
y-4=x+5
y-4=12
y=16
Answer:
118 yards
Step-by-step explanation:
Tamia is getting balloons for her father's birthday party
She wants each balloon to be 6 feet long
Tamia wants to get 59 balloons
Therefore the yards of string needed can be calculated as follows
= 59×6
= 354 feet to yards
= 118 yards
Hence the number of yards needed is 118 yards
