In a game, there are 12 identical balls of which seven are red and five are green. Five red balls and two green balls have number ‘2’ written on them. The rest of the

red balls have number ‘1’ written on them, and the rest of the green balls have the

number ‘3’ written on them. A random sample of three balls is selected without

replacement. Let denotes the event that all the balls selected are red and

denotes that the sum of numbers of the three balls is equal to 6. Calculate:

(i) P(A) ,

(ii) P(B),

(iii)P ( A∩ B),

(iv)P(A|B).​

Two language majors, anna and megan, took exams in two languages. anna scored 85 on both exams. megan scored 74 on the first exam and 85 on the second exam. overall, student scores on the first exam had a mean of 82 and a standard deviation of 4, and the second exam scores had a mean of 71 and a standard deviation of 13. a) to qualify for language honors, a major must maintain at least an 85 average across all language courses taken. so far, which of anna and megan qualify? b) which student's overall performance was better?
