The probability that it is friday and that a student is absent is 0.03. since there are five school days in a week, the probability that it is friday is 0.2. what is the probability that a student is absent given that today is friday?

0.15

Step-by-step explanation:

We have been given that the probability that it is Friday and that a student is absent is 0.03. Since there are five school days in a week, the probability that it is Friday is 0.2.

To solve the given problem, we will use conditional probability formula.

, where,

P(B|A) = Probability of event B given A.

P(A and B) = Probability of event A and B.

P(A) = Probability of event A.

Therefore, the probability, that a student is absent given that today is Friday, would be 0.15.

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
