theoretical probability?

Question

i need help? i dont get it. can someone give all the answers to me or give me some tips. here it is:

lesson 10-4 practice b theoretical probability

AN EXPERIMENT CONSISTS OF ROLLING ONE FAIR DNUMBER CUBE. FINE THE PROBABILITY OF EACH EVENT.

number 1: P(3)
number 2: P(7)
number 3: P(1 or 4)
number 4: P( not 5)
number 5: P( <5)
number 6: P(>4 )
number 7: P(2 or odd)
number 8: P(3) ( equal or <)

PART 2:

AN EXPERIMENT CONSISTS OF ROLLING TWO FAIR NUMBER CUBES. FIND THE PROBABILITY OF EACH EVENT.

9: P( total shown = 3 )
10: P( total shown = 7 )
11: P( total shown = 9 )
12: P( total shown = 2 )
13: P( total shown = 4 )
14: P( total shown = 13)
15: P( total shown = (equal to or < 8 )
16: P( total shown = (equal to or < 12)
17: P ( total shown = ( < 7)

18: A BAG CONTAINS 9 PENNIES, 8 NICKELS, AND 5 DIMES. HOW MANY QUARTERS SHOULD BE ADDED TO THE BAD SO THE PROBABILITY OF DRAWING A DIME IS 1/6?

19: IN A GAME TWO FAIR NUMBER CUBES ARE ROLLED. TO MAKE THE FIRST MOVE, YOU NEED TO ROLL A TOTAL OF 6,7, OR 8. WHAT IS THE PROBABILITY THAT YOU WILL BE ABLE TO MAKE THE FIRST MOVE?

one who gives me correct answers will get 10 points!
