Help urgent In a class of 35 students 15 of them have cats 16 have dogs 3 hangs none how many probability does have both

9/25

Step-by-step explanation:

Number of student who has cat , dog = 25 - 3 = 22

Number of students who has cat and dogs = (15 + 16) - 22

                                                                       = 31 - 22 = 9

Number of students who has only cats = 15 - 9 = 6

Number of students who has only dogs = 16 - 9 = 7

P(Cat & dog) = 9/25

i belive those are the ones that are under 90 degreese.
