Every person has blood type 0, A, B, or AB. A random
group of people are blood-typed, and the results are
shown in the table
Use the table to determine the following probabilities,
The probability that a randomly chosen person from
this group has type B is
The probability that a randomly chosen person from
this group has type AB is
The probability that a randomly chosen person from
this group has type B or type AB blood is

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.

The atomic number, or number, is the described as the number of in the nucleus of an chemical element.

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
