The answer is 7/9
P(A or B) = P(A) + P(B) - P(A and B)
P(A) = 11/18
P(B) = 5/18
<span>p(A and B) = 2/18
</span>P(A or B) = 11/18 + 5/18 - 2/18 = (11 + 5 - 2)/18 = 14/18 = 7/9

Answer:
Step-by-step explanation:
18 stickers------1 page
212 stickers------x pages
For this we can write equation like that:
18*X = 212*1
18x=212
X=11.7777= It means Fiona needs 12 pages for using all these stickes.
0.000000001=0.1
0.000000001=10^9
0.000000001=10^9x10^9=01
0.000000001=10^-9 =0.1
=10^-9 x 0.1
