and

36

Answer 1

(C) j/j+80 and 36/k+36

Explanation:

From the table attached :

Total Email (positive + negative) = j + 80

Number of positive Emails = j

Fraction of positive emails = (number of positive / total number of emails) = j / (j + 80)

Total phone calls (positive + negative) = 36 + k

Number of positive Emails = 36

Fraction of positive emails = (number of positive / total number of emails) = 36 / (k + 36)
