Answer: $\dfrac{3}{7}$

Step-by-step explanation:

From the given table, the total number of flowers = 315

The total number of yellow flowers = 135

Then , if a flower is picked at random, the probability of getting a yellow flower is given by :-

$\text{P(Yellow)}=\dfrac{\text{Number of yellow flowers}}{\text{Total number of flowers}}\\\\\text{P(Yellow)}=\dfrac{135}{315}=\dfrac{3}{7}$

Therefore, the probability of getting a yellow flower is $\dfrac{3}{7}$

Answer 50:50

If you add 105 and 210 together you get 315 which is equal to the number of yellow flowers alone

$4k-20k^9=4k(1-5k^8)=4k\left[1^2-(k^4\sqrt5)^2\right]\\\\=4k(1-k^4\sqrt5)(1+k^4\sqrt5)=4k\left[1^2-(k^2\sqrt[4]5)^2\right](1+k^4\sqrt5)\\\\=4k(1-k^2\sqrt[4]5)(1+k^2\sqrt[4]5)(1+k^4\sqrt5)\\\\=4k\left[1^2-(k\sqrt[8]5)^2\right](1+k^2\sqrt[4]5)(1+k^4\sqrt5)\\\\=4k(1-k\sqrt[8]5)(1+k\sqrt[8]5)(1+k^2\sqrt[4]5)(1+k^4\sqrt5)$

$3b^2-108=3(b^2-36)=3(b^2-6^2)=3(b-6)(b+6)$

$Used:\ (a-b)(a+b)=a^2-b^2$
