Hey can you please help me posted picture of question

Answer 1

Total number of chips = 4+ 6 = 10
Number of white chips = 4

Probability of picking a white chip = $\frac{4}{10}= \frac{2}{5}$

This white chip is not replaced back into the bag. This will reduce the number of white chips in the bag by 1 and reduce the total number of chips in the bag by 1.

So, now the total number of chips in the bag = 3 + 6 = 9
Number of white chips in the bag = 3

Probability of picking a white chip = $\frac{3}{9}= \frac{1}{3}$

Thus, the probability of picking two white chips will be = $\frac{2}{5}* \frac{1}{3}= \frac{2}{15}$

Therefore, option B gives the correct answer.
