Answer:
14/81
Step-by-step explanation:
The probability of getting a green is number of green sections ÷ total number of sections = 2/4+3+2 = 2/9
Probability of not getting a green is = 1 - probability of getting a green = 1 - 2/9 = 7/9
Now we calculate the probability of not getting 2 consecutive greens. I.e probability of getting a green the first time and not getting it the second time= (2/9 × 7/9) = 14/81

<h3>Solution</h3>
It can be convenient to rewrite f(x) as a square, then do the substitution. That way, the algebra is simplified a little bit.
... f(x) = (x +1)²
... f((2a-3)/5) = ((2a-3)/5 +1)² = ((2a -3 +5)/5)²
... = (2/5(a+1))²
... f((2a-3)/5) = (4/25)(a² +2a +1)

Answer:
28%
Step-by-step explanation:
<u>Divide the numerator by the denominator in order to convert this fraction into a decimal.</u>
7/25 = 0.28
<u>Multiply the decimal by 100 to convert into a whole number.</u>
.28 * 100 = 28
<u>7/25 converted into a percent is 28%.</u>
