Answer:
16. 3/8 chance to get an O from jar A, 1/11 chance to get an O from jar B. chance of both happening is 3/88 since the probability multiplies.
17. there are 4 ns or ts. picking one of them from jar b holds a 4/11 chance
18. the chance of picking an n from jar B is 2/11 then, one letter will be removed so the chance of picking a t after that is a 2/10 chance. Together thats a 4/110 chance.
19. vowels are a e i o u. there is one a and 3 o's in colorado. Picking a vowel the first time is a 4/8 chance. Once one is removed, there remains a 3/7 chance of picking another vowel. Together 12/56 chance
20. A consonant is a letter which is not a vowel. There are 4 of those in jar A. Therefore there's a 4/8 chance of picking one. After that, it is put back into the jar. The probability of picking a vowel then is 4/8. Together thats a 16/64 chance
21. There are 5 letters which are NOT o in jar A. Therefore, there is a 5/8 chance probability of picking a letter that is not O
