Answer: 
Step-by-step explanation:
<u>Given function</u>
f(x + 1) = x + 2
<u>Isolate [ x + 1 ] on the right-hand side</u>
f(x + 1) = x + 1 + 1
f(x + 1) = (x + 1) + 1
<u />
<u>Substitute [ x + 1 ] with x</u>
f(x) = x + 1
<u>Substitute [ x ] with [ x - 1 ]</u>
f(x - 1) = (x - 1) + 1
Hope this helps!! :)

Answer:
Step-by-step explanation: The expected loss is 50 cents, we know that it is more likely to lose than win. It is therefore difficult to get-50, so the overall difference between the two possibilities is 2, 50/200=1/4, and the probability to win is 1/4, and the probability to lose is 3/4. Since (1/4)*3=3/4, the number of black balls is 3 times the number of white balls, so k=15.
