A jar contains
4
red marbles,
4
green marbles, and
5
blue marbles.
If we choose a marble, then another marble without putting the first one back in the jar, what is the probability that the first marble will be blue and the second will be green?
GIVE ME THE ANSWER AS A DECIMAL NUMBER, ROUND TO THE HUNDRETH

1/4 because there is 4 grades.

step-by-step explanation:

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
