Look at the relative frequency table above. What is P(X = 9) assuming the table represents all possible outcomes?
Solution
The table provided does not include a value for P(X = 9). However, since the table represents all possible outcomes, the probabilities should add up to 1.
Given the probabilities for X = 3 and X = 12, we can calculate the missing probability:
P(X = 3) = 0.046 P(X = 12) = 0.21
Adding these together gives 0.046 + 0.21 = 0.256.
Since all probabilities should add up to 1, we can find the missing probability by subtracting the sum of the given probabilities from 1:
1 - 0.256 = 0.744
Therefore, assuming the table represents all possible outcomes, P(X = 9) would be 0.744.
