Michael has a bus rental agency. He has 18 buses available, of which 8 have air conditioning (A.C.). What is the probability tha
Inessa05 [86]

Answer:

4 / 9

Step-by-step explanation:

Solution:-

- Michael bus rental agency has a total of n = 18 buses.

- Out all the available buses he has r = 8 buses with AC in them.

- If we were to randomly select a bus from his agency what is the probability that the bus would have an AC:

           P ( Bus with AC ) = Favorable Outcomes / Total outcomes

                                        = Number of bus with AC / Total Buses

                                        = r / n

                                        = 8 / 18

                                        = 4 / 9

Mr and mrs Jackson have 14 grandchildren. Find the ratio of girls to boys if there are four more girls than boys
natulia [17]

Answer:

5 boys to 9 girls

Step-by-step explanation:

Let x = the number of boys

Boys = x

Girls = x + 4

x + (x + 4) = 14

2x + 4 = 14

2x = 10

x = 5

This means that there are 5 boys. Since girls = x + 4, 5 + 4 = 9. There are 5 boys and 9 girls.

I hope this helped and please mark me as brainliest!
