Answer 2

Answer:

The probability of selecting a yellow coloured flower being randomly selected from the garden is found to be 0.6125.

Step-by-step explanation:

As there is a 70% chance of selecting roses from a garden full of flowers and the rest are lillies, i.e., 30% are lillies.

Let us assume there are hundred flowers, so according to question, 70 of them are roses and 30 of them are lillies.

Now, we are also given that $\frac{1}{2}$ of the roses are yellow, so the number of yellow roses will be:

$\frac{1}{2}\times70=35$

Similarly, we are given that $\frac{7}{8}$ of the lillies are yellow, so the number of yellow lillies will be:

$\frac{7}{8}\times30=26.25$

So, the total number of yellow flowers in the garden are:

$=35+26.25$

$=61.25$

Now the probability of finding a yellow flower randomly from the garden is:

$P(a\ yellow\ flower)=\frac{61.25}{100}$

or we can say:

$P(a\ yellow\ flower)=0.6125$

Thus, the probability of selecting a yellow flower randomly from the garden is found to be 0.6125.
