after 28, there were 14 below 3 and 14 above 2. So, what do you think? Check the last two throws.
30*3 = 90
The sum of 28 throws was 78, so the last two had to add up to 12.
a six-faced die was thrown 28 times. the table shows the number that each possible score occurred.
score 1 2 3 4 5 6
frequency 8 6 6 2 4 2
(a) After the 27th throw the median score was 2. what was the least possible score on the 28th throw?
(b) The die was then thrown twice more. The mean score of all 30 throws was exactly 3. What were the scores on the two throws?
