Ashipment contains 10 good and 4 defective bulbs. if three bulbs are selected without replacement, determine the probability the third is defective given the first two are good.

1/3

Step-by-step explanation:

Since you know the first two are good, they do not factor in. The only difference now is your total.

You had a total of 14 bulbs, but two were removed and we know they're good.

Now you have a total of 12 bulbs. 4 are still defective. Your probability of pulling a defective one is 4/12, or reduced, 1/3.

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.
