The probability that person A will pass Finite Mathematics is 7/8 and the probability that person B will pass is 4/7 . Assume the events are independent. Find the probability that person A will fail given that person B will pass.

0.1429 is the required probability.

Step-by-step explanation:

We are given the following in the question:

The probability that person A will pass Finite Mathematics =

The probability that person A will pass Finite Mathematics =

The two events are independent.

We have to find the conditional probability  that person A will fail given that person B will pass.

Thus, 0.1429 is the probability that person A will fail given that person B will pass.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
