Answer #1
  • The total ways 2 vowels can be chosen from the given list of alphabets {B,E,O,P,R,W} is, choosing 2 elements (E,O) is 1 way, as both E and O can be chosen from the given set in only 1 way.
  • The given set {B,E,O,P,R,W} contains 6 elements and 3 elements (letters) can be chosen from this given set of 6 elements in
  • Similarly as the first case, in the given set, there are 4 consonents {B,P,R,W} and these four can be chosen from the given set only in one way. Hence the solutions.

4. The Hawaiian alphabet has twelve letters: five vowels (a, e, i, o, and u) and seven consonants (h, k, l, m, n, p, and w). For the purpose of this exercise we will define an n–letter “word” as an ordered collection of n of these twelve letters with repeats allowed. Obviously, most such “words” will be nonsense words.   e) What is the probability a randomly selected four–letter “word” contains exactly one consonant?
