Answer:

p(A) = 0.55

p(b) = 0.45

Step-by-step explanation:

Experimental probability = \frac{Number of favorable outcomes}{Total number of outcomes}

total students = 55 + 45   ⇒ 100

let A be the probability that students brought lunch from house = \frac{55}{100} ⇒ 0.55

let B be the probability that students order school lunch = \frac{45}{100} ⇒ 0.45
