Number of yellow notepads = 6
Number of Blue notepad = 6
Number of green notepads = 6
Number of pink notepads = 6
Samole space for experiment :
(Number of different distinct notepads * Number of notepads in each)
(4 * 6) = 24
Step-by-step explanation:
Let n be the age of the youngest sister. Since the ages are consecutive odd integers, the next sister's age is n+2, and the oldest sister is n+4. the following equation represents the relationship between the girls' ages.
n + 3(n + 4) = 5(n + 2) - 5
n + 3n + 12 = 5n + 10 - 5
4n + 12 = 5n +5
-4n -5 -4n -5
7 = n
so the sisters are 7, 9, and 11
