There is a bag filled with 5 blue and 4 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is replaced.
Another marble is taken at random.
What is the probability of getting 2 that are different in colour?

Respuesta :

The bag of marbles has a 25% chance if that, so actually, let me say 15% of it being a different color. Over 50 percent is blue, so yes.
