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%.
Answer:
One fourth of the caps are blue with tassels.
Step-by-step explanation:
Take 7/11 of the caps with tassels, which boils down to (7/11)(11/28), or 1/4.
One fourth of the caps are blue with tassels.
Hey there, hope you are having a wonderful day! :)
Let's solve this inequality.
First of all, let's move all the numbers to the right, using the 
:
Now, let's move the variables to the left:
Now, as you can see, we ended up with a false statement. 0 is NOT greater than 5.
Thus, there are no values of x that make the inequality true, and the inequality has
Hope you find it helpful.

Answer:
Brian can read 0.4 or 4/10 in 1 hour
Step-by-step explanation:
The answer is 4/10 because 20 multiplied by 3 is 60, which equals 1 hour.
So, 2/15 times 3 = 4/10
