12.5 different groups. To find this you should divide the total number of people by the number required in a jury. Say 150/12=12.5 which is my final answer
For the answer to this question, I'll support it with solutions
Each jury has 12 members in it right? 
 50 members divided on the number of juries right 
1 jury ---> 12 members 
x juries ---> 150 members 

x = (150*1) / 12 = 12.5 juries
