What is 100+100+56+88+90=
then divide all of the numbers

86.8

Step-by-step explanation:

100+100+56+88+90

divide the answer by 5

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.
