Answer:
(a)[tex]\dfrac{15}{32}[/tex]
(b) 17:15
Step-by-step explanation:
(a)
The roulette wheel has 32 slots (inclusive of 0 and 00)
Number of Odd Numbers between 1 to 30 =15
Since you are placing a bet that the outcome is an odd number.
[tex]P(\text{Winning})=\dfrac{\text{Number of Odd Numbers}}{\text{Total Number of Slots}} \\=\dfrac{15}{32}[/tex]
(b) The actual odds against winning
[tex]\text{Actual Odds against Winning})=\dfrac{32-15}{15}\\=\dfrac{17}{15}[/tex]
Therefore, the actual odds against winning are 17:15
