seventh grade. Also, 40 students in the choir are girls; 18 of them are in seventh grade. What is the probability that a student picked at random from the choir is either a girl or is in seventh grade?
ehm... you need to put the answers on the options as we cant give you and answer without a option to pick but another thing is we need to know the rest of the numbers as you cant make a answer to how many of X and T are in Y if you dont have T or Y
