Answer:

Step-by-step explanation:

There are 44 slots with numbers 0 , 00 , 1 ,2 ...42

Bet is placed for an odd number

Total odd numbers are = 1,3,...41 = 21

Total numbers = 44

a) Probability of winning=n(odd numbers)/total numbers

= \frac{21}{44} \\=0.4773

b) Actual odds against winning = \frac{0.4773}{1-0.4773} \\=0.9131

c) Pay off odds are 1:1.

So profit if we bet 14 dollars = 14 (0.9131) = 12.7833

d) If pay off is the same as 0.4773:0.5227=0.9131:1

Profit would be =0.9131*0.9131=\\0.8338
