) Mila creates a tree diagram to show all possibilities for flipping a coin four times. How many possibilities are in the sample space at the end of the tree diagram?

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
