where n! = n(n - 1)(n - 2).... × 3 × 2 × 1
Thus
9
=
← cancel the terms of 6! on numerator/denominator, leaving
= 9 × 8 × 7 = 504
5X^2 - 45
5(X^2 - 9)
5(X - 3)(X + 3)
4X^2 - 324
4(X^2 - 81)
4(X - 9)(X + 9)

Answer:
The probability of cured people in who took the remedy is 8/9.
Step-by-step explanation:
Success rate of the cold remedy = 88%
