Answer:
[tex]\sf \dfrac{9}{169}[/tex]
Step-by-step explanation:
The bag has:
- 6 blue chips
- 13 pink chips
- 7 white chips
⇒ Total number of chips = 6 + 13 + 7 = 26
Probability Formula
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Probability of choosing a blue chip from the first draw:
[tex]\implies \sf P(Blue)=\dfrac{6}{26}[/tex]
As the chips are replaced, the probability of choosing a blue chip from the second draw is the same as the first.
Therefore, the probability of taking out a blue chip in both draws is:
[tex]\begin{aligned}\implies \sf P(Blue)\:and\:P(Blue) & = \sf \dfrac{6}{26} \times \dfrac{6}{26}\\\\& = \sf \dfrac{6 \times 6}{\26 \times 26}\\\\& = \sf \dfrac{36}{676}\\\\& = \sf \dfrac{36 \div 4}{676 \div 4}\\\\& = \sf \dfrac{9}{169}\end{aligned}[/tex]
