Match each description with its symbolic representation.

1. p (a)
2. p (a ∩ b)
3. p (a ∪ b)
4. 1 - p (a ∩ b)
5. 1 - p (a ∪ b)
6. p (a | b)

a).the probability that both events a and b do not occur together, but either may occur by itself
b.)the probability that event a occurs given the fact that event b occurs
c.)the probability that neither event a or event b occurs
d.)the probability that both event a and event b occur
e.)the probability that event a occurs
f.)the probability that either event a or event b occurs

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.
