Probability is the likihood of something happening. Example: on a dice 1-6, the probabilty of you getting a 5 out of 6 (5/6)
1/2 : 2/3 is 3/4 then 3/4 is 3/4
- 5/8 + 4/5 =
- 25/40 + 32/40 =
7/40
6x+ 3y+ 1 would be your answer because all you have to do is find the like terms and conbine them until you get your answer
