Answer 2

Answer:

$\frac{2}{5} \: or \: 40 \: \%$

Step-by-step explanation:

Total balls in the bag [n(s)] = 10 (addition of all colors of balls)

No. of red balls: n(r) = 4

Therefore,

Probability of getting a red ball:

Probability of getting a red ball:$p(r) \: = \frac{n(r)}{n(s)} \\ \: \: \: \: \: \: \: \: \: \: = \: \frac{4}{10} \\ \: \: \: \: \: \: \: \: \: \: = \frac{2}{5}$

or

$\frac{2}{5} \times100 \\ 2 \times 20 \: = 40\ \%$
