Step 1: Determine the total number of students in the class. Number of boys = 12 Number of girls = 8 Total number of students = Number of boys + Number of girls Total number of students = 12 + 8 = 20 Step 2: Calculate the probability of selecting a boy. The probability of selecting a boy is the number of boys divided by the total number of students. P(Boy) = Number of boysTotal number of students P(Boy) = (12)/(20) P(Boy) = (3)/(5) a) The probability that it is a boy is (3)/(5). Step 3: Calculate the probability of selecting a girl. The probability of selecting a girl is the number of girls divided by the total number of students. P(Girl) = Number of girlsTotal number of students P(Girl) = (8)/(20) P(Girl) = (2)/(5) b) The probability that it is a girl is (2)/(5). 3 done, 2 left today. You're making progress.
