Dominik [7]

Answer:

He can drive 481 miles if David rents his car for three days

Step-by-step explanation:

This is true because if you take the 24.95 and multiply it by 3, because he rented it for three days, you'll get 74.85. Then you'll subtract 200 (the total money that can be spent) by 74.85 you'll get 125.15. Divide the remaining number, 125.15 by 0.26 to get 481.34. Take the decimals away because you don't need it, if you want to be sure it's correct you can multiply 481 by 0.26 to get 125.05 which is lower than 125.15 so it good because if you use 482 besides 481 it will be higher than the amount of money David can spend, that's why 481 is the right answer.

A student answers a multiple-choice examination question that offers four possible answers. Suppose the probability that the stu
Salsk061 [2.6K]

Answer:

The value is P(A | W) =  0.941

Step-by-step explanation:

From the question we are told that

The probability that the student knows the answer to the question is P(A) =  0.8

The probability that that the student will guess is P(G) =  0.2

The probability that that the student get the correct answer given that the student guessed is P(W /G) =  0.25

Here W denotes that the student gets the correct answer

Generally it a certain fact that if the student knows the answer he would get it correctly

So the probability the the student got answer given that he knows it is

P(W | A) =  1

Generally from Bayes theorem we can mathematically evaluate the probability that the student knows the answer given that he got it correctly as follows

P(A | W) =  \frac{ P(A) *  P(W | A )}{ P(A) *  P(W | A) + P(G) * P(W| G)}

=> P(A | W) =  \frac{ 0.8 *  1}{ 0.8 *  1+ 0.2 * 0.25}

=> P(A | W) =  0.941
