Question

I need help in this section please!!

Answer 1

Answer:

$\frac{1}{25}$

Step-by-step explanation:

Probability of first yellow ball$=\frac{total\ yellow\ ball}{Total\ ball}=\frac{2}{10}=\frac{1}{5}$

Since first ball is again placed in the bag

Probability of second yellow ball$=\frac{total\ yellow\ ball}{Total\ ball}=\frac{2}{10}=\frac{1}{5}$

These two are independent events so the probability of both yellow balls=$=\frac{1}{5} \times \frac{1}{5} =\frac{1}{25}$
