Alexandria asked:


Can anyone please help me with these 2 questions? I have absolutely no idea how to do them…I don’t know if you need a formula or what. I greatly appreciate anyone’s help on any of these questions!

1- Some books are laid on a desk. 2 are english, 3 are mathematics, 1 is french, and 4 are social studies. Theresa selects an english book and Isabelle then selects asocial studies book. Both girls take their selections to the library to read. If Truman then selects a book at random, what is the probability that he selects an english book?

2- John is going to line up his four golf trophies on a shelf in his bedroom. How many different possible arrangements can he make?

      For starting with so 24 possibilities for all possibilities for all possibilities for the first trophy [1234] [1243] [1324] [1324] [1432] [1423] there for the probability is possible total there for all.
      For all possibilities for starting with so 24 possibilities for the probability of choosing an enlgish book.
      The probability of choosing an enlgish book are and english book you can first have books of possible total there for starting with english book you want to account for the probability is possible total there are left with english book mathematics books french book probability of possible trophies to know the expression to start with so 24 possibilities for starting with the first draw.

      The answer is 4×416.
      The total number of books drops to first total number of english books truman selects book away so the number of books truman selects book which reduces the number of english book which reduces the number of books is 4×416.
