Fiona needs to choose a five-character password with a combination of three letters and the even numbers 0, 2, 4, 6, or 8.
If she uses her initials, F, J, and S in order as the first three characters, and she does not use the same digit more than once in
her password, how many different possible passwords are there?
10
20

B. 20

Step-by-step explanation:

given that the chosen student is a female, the probability that the student chose invisibility as their superpower is 2/3 or 0.67

Step-by-step explanation:

Here we have a question on conditional relative frequency;

                               Males                   Females                     Total

Fly                           30                         10                                40

Invisibility                12                          32                               44

Other                       10                          6                                 16

Total                        52                         48                               100        

Given that the chosen student is a female, the probability that the student chose invisibility as their superpower is found as follow;

Hence we look for the conditional relative frequency of the second row forr females corresponding to invisibility as their preferred super power is therefore;

Conditional relative frequency =

Conditional relative frequency = 2/3

Therefore, given that the chosen student is a female, the probability that the student chose invisibility as their superpower = 2/3.
