Answer:
Probability that a randomly selected student plays sport and is in band = 1/50
Step-by-step explanation:
Total number of students= 1900
Percentage of those that play sport and are in band = 2%
Hence those that play sport and are in band = 2/100 x 1900 = 38 students
Probability that a randomly selected student plays sport and is in band = 38/1900 = 1/50

This is material out of the lesson of basic mathematics of compound probability. 
To solve this problem, we first must count the number of outcomes (n) for this experiment. There are 2 rows of 4, so there are 8 outcomes. Now we must find what exactly the answer is looking for.
The answer is looking for the answer to the compound probability statement; P( A then B then A). If you look at the table of outcomes (results), there is one result that matches ABA. So, find the number of specific outcomes from the set of events and divide it by the total number of outcomes. 
Solution:
1/8= 0.125
