answer for the question​

Answer 1

Answer:

(c) $\frac{77}{144}$

Step-by-step explanation:

First we will add all balls: 5+4+3+5= 17

Then we will add all red balls: 4+5=9

Dividing total number of red balls by the total number of balls, we get:

$\frac{9}{17}$

Since it is not one of the options, we have to find an option which is proportionate to this fraction.

77=9*8.5

144=17*8.47                    

(8.47 is can be rounded to 8.5 so we will consider it as the same proportion)

Therefore the answer is  $\frac{77}{144}$
