Answer:
Odds in favor are 3:7
Odds against are 7:3
==============================================
Step-by-step explanation:
The probability Merle wins is 30% or 0.30
0.30 as a fraction is 30/100 = 3/10.
Merle would win 3 times and lose 10-3 = 7 times if attempting 10 tries.
The odds in favor are 3:7 to represent the ratio of 3 wins to 7 losses.
The odds against are 7:3 which is the reverse of the previous ratio.
