Step-by-step explanation:

Probability of:

Winning = (0.1) or 10%

Losing = (0.9) or 90%

"Odds for" winning: 1:9

"Odds against" winning: 9:1

6, 15, 24, 33

Step-by-step explanation:

Basically, the number on top of the sigma represents the number of terms total in that sequence, and on the right you have the equation in which you can plug in whichever value that falls into what the top number says to find the output. In other words, just plug in 1 for k to find a1, 2 for k to find a2, etc.

Hope that helps!
