E(X)=2.20−3.20=-1.00cap E open paren cap X close paren equals 2.20 minus 3.20 equals negative 1.00 ✅ Final Answer

E(X)=(95×0.01)+(15×0.05)+(5×0.10)+(0×0.20)+(-5×0.64)cap E open paren cap X close paren equals open paren 95 cross 0.01 close paren plus open paren 15 cross 0.05 close paren plus open paren 5 cross 0.10 close paren plus open paren 0 cross 0.20 close paren plus open paren negative 5 cross 0.64 close paren fifa-22-pc-game-free-download

Next, list or calculate the probability for each outcome. The problem gives most of them directly, but we need to calculate the probability of winning nothing: Probability of Probability of Probability of Probability of To find the probability of winning nothing (losing ), subtract the sum of the winning probabilities from E(X)=2

First, find the net profit or loss for every possible ticket outcome by subtracting the initial cost of the ticket from the prize amounts: Winning nothing: 2. Determine all outcome probabilities Identify all net payouts E(X)=0

Here is the step-by-step procedure to calculate this result: 1. Identify all net payouts

E(X)=0.95+0.75+0.50+0−3.20cap E open paren cap X close paren equals 0.95 plus 0.75 plus 0.50 plus 0 minus 3.20

P(nothing)=1−(0.01+0.05+0.10+0.20)=1−0.36=0.64cap P open paren nothing close paren equals 1 minus open paren 0.01 plus 0.05 plus 0.10 plus 0.20 close paren equals 1 minus 0.36 equals 0.64 3. Apply the expected value formula
