A circle is divided into 9 uneven pies shaped pieces. Each section is labeled 1, 2, ..., 9 the circle is then spun and the number pointing north recorded. Estimate the probability that the next number pointing north will be between 2 and 7

To estimate the probability that the next number pointing north will be between 2 and 7, we need to count the number of times a number between 2 and 7 appears and divide it by the total number of spins.
From the given sequence: 4 3 2 1 9 8 5 6 7 4 3 2 1 5 8 6 5 4, we can see that the numbers between 2 and 7 that point north are: 2, 5, 6, and 4. So, there are a total of 4 occurrences of a number pointing north between 2 and 7.
To find the total number of spins, we count all the numbers in the sequence: 4 3 2 1 9 8 5 6 7 4 3 2 1 5 8 6 5 4. There are 18 numbers recorded.
So, the probability is calculated by dividing the number of favorable outcomes (4) by the total number of possible outcomes (18):
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 4/18 = 2/9
Therefore, the estimated probability that the next number pointing north will be between 2 and 7 is 2/9.
