A bag contains 3 red, 5 black, and 7 white balls. You take them out, one at a time, without looking. What is the least number of balls you need to take out of the bag to be sure you get at least one ball of each color?

its rather 3 or 5 its prob 3

Step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

its a straight line parallel to the time axis
