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

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

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

=> $P(A | W) = 0.941$

Can someone please answer A and B please?

marta [7]

2 bags

7 apples

A) Instead of a lets say:

a = 1, 2 , 3

If a =1 then, (you already know there are 2 bags) you have 1 apple in each bag, making total of 2 apples

If a =2 then you are having 2 apples in each bag making total of 4 apples

If a =3, 3 apples in each bag, making total of 6 apples

Conclusion:

2 * 1 = 2

2 * 2 = 4

2 * 3 = 6

See the difference & pattern here

Now lets do with a

2 * a = 2a

B) If a = 6

then, 2*6 = 12

lets continue from a =3

2*4=8

2*5=10

2*6=12

See the pattern again
