3 x 3 x 3 x 3 x 3 x 3 x 3 x 3
Step-by-step explanation:
22.
14-1.5 = 12.5
16-1.5 = 14.5
Put a dot at 12.5 and a dot at 14.5 then connect them with a line and write (1.5 added) below the graph
Greater than 20 because 5×6=30 so it passed
Answer: b. It's a fair method because each result is an equally likely possible outcome.
The number of students is same as the number of the sides of the dice. In this scenario, the school principal will roll two dices three times and the number that repeated most will be chosen. For every dice, all number will have equally likely possibility so the randomization is fair(1/6 chance for every student).Rolling the dice >1 times will have a problem because there is a high chance to get draw result. It doesn't have any correlation with fairness though.
