On each bet a gambler loses $1 with probability .7, loses $2 with a probability .2, and wins $10 with a probability .1. estimate the probability that the gambler will be losing after 100 bets.
this is supposed to be done with the normal distribution approximation. my values keep coming off slightly from the book though

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

answer: what statements
