The probability that john will drive to school is 0.31, the probability that he will ride with friends is 0.12, and the probability that his parents will take him is 0.57. he is not allowed to have passengers in the car when he is driving. what is the probability that john will have company on the way to school? p( john will have company on the way to school is what

P(company) = P(ride with friends) + P(with parents) = .23 + .4 = .63 0r 63%

Step-by-step explanation:

The 3 different case scenarios are independent of one another:.37 + .23 + .4 = 1

P of two of them occurring is found by adding their individual Probabilities

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
