Abag contains and 9 metal balls, 10 hollow balls, 4 glass balls and 18 plastic balls. what is the probability of choosing a glass or hollow ball? 1. 35.4%2. 34.1%3. 24.6%4. 38.9%

2, 34.1%, since after you add all them up and create a fraction then convert it into a decimal then multiply it by 100 it becomes 34.1

Khalid and Sue's Height together is 126 Inches. The difference is 6 inches, so therefore you subtract 6 from the total getting you 120 Inches. You do this with all of the problems for example: The first one. Sue is 72 inches and Khalid is 54. Add them together and subtract them by 6 to get your final answer. Please DO NOT quote me on this lol. This is how I read the question. I think this is right but I am not absolutely 100% sure. Hope this helps.
