Answer 1

Step-by-step explanation:

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 = 0Read more on Sarthaks.com - https://www.sarthaks.com/845710/kareena-threw-dice-30-times-and-noted-the-number-appearing-each-time-as-shown-below-6-6-5-3-6-2?show=845711#a845711
