Answer:
0.002991
Step-by-step explanation:
Let
User is legitimate one = E₁
User is fraudulent one = E₂
User originates calls from two metropolitan = A
Therefore, according to the question
P(E₁) = 1 - 0.01% = 1 - 0.0001 = 0.9999
P(E₂) = 0.0001
P(A/E₁) = 1% = 0.01
P(A/E₂) = 30% = 0.30
Now,
P(E₂/A) = 
or
P(E₂/A) = 
or
P(E₂/A) = 0.002991
-5x + 12 = 32 Subtract 12 from both sides
-5x = 20 Divide both sides by -5
x = -4
Answer:
what is P(A), the probability that the first student is a boy? 3/5
what is P(B), the probability that the second student is a girl? 3/4
what is P(A and B), the probability that the first student is a boy and the second student is a girl? 1/2
No, évents A and B are not independent events
Step-by-step explanation:
w = width
l = length
w = 1/3 length
l = 7 3/4
w = 1/3 * length
w = 1/3 ( 7 3/4)
change the mixed number to an improper fraction
7 3/4 = (4*7+3)/4 = 31/4
w = 1/3 ( 31/4) = 31/12
12 goes in to 31 2 times with 7 left over
w = 2 7 /12
Answer:
X = -11
Step-by-step explanation:
-2 (x+3) +5x = -39
3x -6= -39
3x = -33
3x/3 = -33/3
X = -11
