At the beginning you have 10 balls, 5 of which are red. So, the chance of picking a red ball with the first pick is
When it comes to the second pick, you have 9 balls (because you didn't replace the first red ball), 3 of which are blue. So, you pick a blue ball with the second pick with probability
The two events will occur one after the other with the product of the probabilities:
7x+-2x=5x
-10+24= 14
14+5=19
The answer is 19. hope this helps!
