Answer:
p(A) = 0.55
p(b) = 0.45
Step-by-step explanation:
Experimental probability = ![\frac{Number of favorable outcomes}{Total number of outcomes}](https://tex.z-dn.net/?f=%5Cfrac%7BNumber%20of%20favorable%20outcomes%7D%7BTotal%20number%20of%20outcomes%7D)
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
Answer:
Step-by-step explanation:65-9=56, 56/2=28, 28+9=37 so 28+37=65
The probability it will be a ride = total number of rides / total attractions.
Probability = 6/16
Probability = 3/8
Answer:
35
Step-by-step explanation:
40=1/2(115-x)
