Question

The number of chips of different colors in Vicky's bag is shown below: 5 blue chips 11 pink chips 9 white chips. Vicky takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Vicky takes out a blue chip in both draws? 5 over 25 multiplied by 5 over 25 equals 25 over 625, 5 over 25 plus 5 over 25 equals 10 over 25, 5 over 25 multiplied by 4 over 24 equals 20 over 600, 5 over 25 plus 4 over 24 equals 220 over 600.

Answer 1

$|\Omega|=25^2=625\\ |A|=5^2=25\\\\ P(A)=\dfrac{25}{625}=\dfrac{1}{25}$
