Probability of creating a mini license plate with an E

A mini license plate for a toy car must consist of a number followed by a T and a vowel. Each number must be a 3, 6, or 9. Use the counting principle to determine the number of points in the sample space. Construct a tree diagram and submit it to the week 5, assignment 2 dropbox. List the sample space. Determine

Probability of first and second players

Please explain in detail... A two-person game is played in which a fair coin is tossed until either the sequence HT (heads, tails) or the sequence TT (tails, tails) appears. If HT appears, the first player wins; if TT appears, the second player wins. Would you rather be the first or second player? Explain.

A particular test for the presence of steroids is to be used after a professional track meet. If steroids are present, the test will accurately indicate this 95% of the time. However, if steroids are not present, the test will indicate this 90% of the time (so it is wrong 10% of the time and predicts the presence of steroids). B
