Answer:
6/5 or 1.2
Step-by-step explanation:
you can solve with an equation:
x : 5 = 12 : 50
x = 5 * 12 : 50
x = 6/5 (or 1.2)
or you can solve with an expression
12/50 * 5 = 6/5 (or 1.2)

It is not possible to select a single group from the primary school, since being a single group it could not in any way represent the entire primary school.
Choosing a group would provide the average height for that group, not the entire primary.
Assumptions can be made that the course of half of the primary would theoretically give us a more accurate representation, but the objective is to select a number of students from each course and there would be a representative sample of the entire primary.
Yo sup??
To find P(A and C) we have to simply multiply the probabilities of getting an A with that of getting a C
P(A)=0.6
P(C|A)=0.3
P(A and C)=0.6*0.3
=0.18
Hope this helps.
