Answer:
1/2
Step-by-step explanation:
A sample space is a collection or a set of possible outcomes of a random experiment.
I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.
To find the probability that the total showing is greater than 9, simply identify the number of values in the sample space that are greater than 9.
(I have highlighted these in yellow).
Therefore, P(X>9) = 8/16 = 1/2

Answer:
0.077
Step-by-step explanation:
From the table :
Number of students aged 31 - 35 = 60
Number of students over 35 = 26
Total number of students = total possible outcomes = 1123
Required outcome = (students aged 31 - 35) + over 35 = 60 + 26 = 86
Probability = required outcome / Total possible outcomes
Probability (at least 31) = 86 / 1123 = 0.0765
= 0.077 (3 decimal places)
