Kareena threw a dice 30 times and noted the number appearing each time as shown below 

3, 6, 5, 4, 4, 3, 6, 5, 3, 6, 2, 3, 1, 6, 4, 1, 3, 6, 1, 1, 2, 4, 4, 3, 3, 4, 2, 1, 2, 1 

Kareena prepared the table using tally marks.

Kareena wanted to extract following information: 

1. The number that appeared the maximum number of times. 

2. The number that appeared the minimum number of the times. 

3. Difference between the number of times odd numbers have appeared and number of times even numbers have appeared.

Best answer

1. Number 3 appeared maximum times (7 times) on dice. 

2. Number 5 appeared minimum times (2 times) on dice. 

3. Difference between the number of times odd numbers have appeared and number of times even numbers have appeared is zero. 

⇒ Frequency of even number occurred ~ Frequency of odd number occurred 

= Frequency of 2, 4, 6 ~ Frequency of 1, 3, 5 

= (4 + 6 + 5) ~ (6 + 7 + 2) = 15 ~ 15 = 0
