Question

Answer 1

Answer:

12

Step-by-step explanation:

there area 4 of them so n=4

since alice and jonna wants to sit together you must divide 4! with 2!

it uses the distinguishable permutation formula which is n!/p!q!r!...

so 4!/2! = 24/2 = 12

also 12 din po yung nakalagay sa answer key so tama po yan
