How do I get ready for a zombie apocalypse?

First you must hoard everything and find anything that you think you might need!

(Just going to say this aloud but I don't think we are going to be having a zombie apocalypse) You might be a little crazy...  

Make sure you go to a very very tall building because zombies can't walk up stairs they can only walk down. Or go to a boat and go into the middle of the ocean because zombies can't swim ^^

Step-by-step explanation:

(NOT researched)

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
