Question

Activity 2 : Divide the class into groups of 2 or 3 students. Let a student in each group toss a coin 15 times. Another student in each group should record the observations regarding heads and tails. Note that coins of the same denomination should be used in all the groups. It will be treated as if only one coin has been tossed by all the groups.] Now, on the blackboard, make a table like Table 15.2. First, Group I can write 1 down its observations and calculate the resulting fractions. Then Group 2 can write down its observations, but will calculate the fractions for the combined data of Groups 1 and 2, and so on. (We may call these fractions as cumulative fractions. We have noted the first three rows based on the observations given by one class of students,​
