A trisomy is a condition in which a person has three copies of a chromosome instead of the usual two copies. Trisomy 9 refers to three copies of chromosome 9. A person can have full trisomy 9 (three copies in every cell) or mosaic trisomy 9 (three copies in some cells but not all).

An average is where you take all the numbers and add them together. You then divide that total by the amount of numbers and it gives you an average number. For example, the average of 5,6,7,8 and 9 - add them to get 35, then divide that by 5 to give an average of 7.
5. 3+6+9+2 = 20 20 / 4 = 5. To calculate the average of a series of numbers you have to add them together and divide them by the amount of numbers given.
