Bag has 4 green marbles 3 red marbles and 3 yellow marbles what is the probability that you pick a green marble do not replace it and pick another green marble

4+3+3 = 10 total marbles

4 are green so 4/10, reduced to 2/5 of picking a green one first.

 without replacing it, there would be 9 marbles and 3 green ( assuming he picked a green one first)

 so 3/9 reduced to 1/3 that the 2nd one would be green

2/5 x 1/3 = 2/15 probability of picking 2 green marbles

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
