Answer:
See proof below
Step-by-step explanation:
We have to verify that if we substitute in the equation
the equality is true.
Let's substitute first in the right hand side:
Now we use the distributive laws. Also, note that (this also works when the power is n-2).
then the sequence solves the recurrence relation.

Check the explanation
Step-by-step explanation:
let the money on bet is X.
probability of winning =18/38=9/19
probability of losing =(1-9/19)=10/19
expected outcome =probability *return =(
Expected value of return after one bet is =(9/19*x)-(10/19*x)=-1x/19
it is negative which is obvious cause casinos are there to earn money.
a) Our best strategy in this case as probability of winning is near by 50 %, we should place a bet of 1 $ each,and when we lose one bet consecutively we should bet twice the amount..
Cause two consecutive losses on black has less probability.
c) In case we have to reach 30 $ we have to use the same strategy as above.
