Answer:
The probability the man was hit by a Blue Cab taxi is 41%.
Step-by-step explanation:
In terms of bayesian probability, we have to calculate P(B|Wr), or, given the witness saw the right colour, the taxi is from the Blue Cab company.
According to Bayes
P(B|Wr) = P(Wr|B)*P(B)/P(Wr)
P(Wr|B) = 0,8
P(B) = 0.15
To calculate P(Wr), or the probability of the witness of guessing right, we have to consider the two possibilities:
1) The taxi is from Blue Cab (B) and the witness is right (Wr).
2) The taxi is from Green Cab (G) and the witness is wrong (Ww).
The total probality of guessing right is
P(B)*P(Wr) + P(G)*P(Ww) = 0.15*0.8 + 0.85*0.2 = 0.29
So we can calculate:
P(B|Wr) = P(Wr|B)*P(B)/P(Wr) = 0.8*0.15/0.29 = 0.41
The probability the man was hit by a Blue Cab taxi is 41%.
Let us assume the first odd number = x
Then the second consecutive odd number = x + 2
The third consecutive odd number = x + 4
The addition of the three consecutive odd numbers = 75
Then we can write the equation as
x + x + 2 + x + 4 = 75
3x + 6 = 75
3x = 75 - 6
3x = 69
x = 69/3
= 23
Then
The greatest odd number in the question = X + 4
= 23 + 4
= 27
So the greatest odd number in the question is 27.
Answer:
$4.46
Step-by-step explanation:
$60- 24.32= $35.68
So $35.68=8 bags of potatoes.
Then ÷8 to find 1 bag.
$35.68 ÷8 = $4.46
$4.46=1 BAG
Answer:
the answer is 176 hope this helps
Step-by-step explanation:
Answer: C. 42
Step-by-step explanation:
(3x + 3) is the same angle as 129.
So, you have to equal them to each other.
3x + 3 = 129
Now you solve.
Subtract 3 from each sides.
3x = 126
Divide 3 from each side.
x=42
