2. Uma has 50 red and 50 blue balls. She has two bowls with her. She has to distribute the balls in these two bowls in such a way that none of the bowls are left empty. If one were to choose one of the two bowls at random and then randomly draw a ball from it, the probability of the ball being red is maximized. After this distribution, there will be a total of how many balls in the bowl with a larger number of balls

5. The speed of a common snail is about 1 mm per second. It secretes a bit of mucus that coats the ground beneath and helps it to move along. This snail we are interested in now has a problem with this secretion so it moves one mm in the first second and in the subsequent seconds, it moves only half the distance covered in the prey second. Algae, the good it cherishes, is at a 3-meter distance from this snail. In how much time will it reach its food?
