Answer:
See below.
Step-by-step explanation:
The 'ac' method. here's an example:
Factor x^2 - x - 6.
Compare with ax^2 + bx + c:
a = 1 and c = -6 so ac = -6.
b = -1 so we try -6 = -3 * 2:
x^2 - x - 6
= x^2 - 3x + 2x - 6
Factor by grouping.
= x(x - 3) + 2(x - 3)
= (x + 2)(x - 3).
In the word replacement, there are 11 letters.
4 of them are vowels : e, a, e, e
7 of them are not vowels : r, p, l, c, m, n, t
The probability of getting a vowel the first try is 4/11.
The probability of getting something that is not a vowel is 7/10. The denominator is one less because the vowel card is not replaced, meaning there is one less card to choose from.
Multiply.
4/11*7/10
=28/110
=14/55
The probability is 14/55.
