    Answer 50:50

    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}
