Answer:
p(A) = 0.55
p(b) = 0.45
Step-by-step explanation:
Experimental probability =
total students = 55 + 45 ⇒ 100
let A be the probability that students brought lunch from house = ⇒ 0.55
let B be the probability that students order school lunch = ⇒ 0.45
okey
you needed the sum or division?
Yes. They are identical triangles which can be seen by the fact that two of their sides are equal. Angle ABC=Angle CBA
They are identical isosceles triangles.
20100
There are 200 numbers in this addition problem. To add this, we can do 1 + 200, 2 + 199, 3 + 198 and so on. All of these pairs have a sum of 201 and since there are 200 / 2 = 100 pairs the answer is 201 * 100 = 20100.
