Answer:
3/5
Step-by-step explanation:
the probability of winning + probability of not winning must = 1
these are the only 2 options
2/5 + not winning = 1
subtract 2/5 from each side
not winning = 5/5-2/5
not winning = 3/5
it is 3 out of five.
2/5 is the part 5 is the whole so 5 minus 2 is 3 meaning 3/5 is the probability of not winning.
Add 8 to both sides
12x = 40 + 8
Simplify 40 + 8 to 48
12x = 48
Divide both sides by 12
x = 48/12
Simplify 48/12 to 4
<em>x = 4</em>
<u>Answer: A. 4</u>
It would be the first one... 10:25
10/4=2.5
2.5*10=25
2.5*4=10
