The jack in the box franchise in bangor, maine, has determined that the chance a customer will order a soft drink is 0.90. the probability that a customer will order a hamburger is 0.60. the probability that a customer will order french fries is 0.50.the restaurant has also determined that if a customer orders a hamburger, the probability the customer will also order fries is 0.80. determine the probability that the order will include a hamburger and fries.

0.48

Step-by-step explanation:

Given : The probability that a customer will order a hamburger P(H)= 0.60.

The probability that a customer will order french fries P(F)= 0.50.

The restaurant has also determined that if a customer orders a hamburger, the probability the customer will also order fries : P(F|H)= 0.80.

Using conditional probability formula , for any event A (first event) and B (second event), we have:-

Similarly, the probability that the order will include a hamburger and fries :-

Hence, the probability that the order will include a hamburger and fries=0.48

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
