For 1 play, the chance of gaining $8 is 4/38, while the chance of losing the $1 is 34/38. Therefore, the expected value is ($8)(4/38) + ($-1)(34/38) = $(-1/19). Over 50 plays, which are mutually independent of each other, we multiply the number of plays by the expected value to get $(-50/19) = $-2.63.

Answer:
154,226 - (154,226 * 104) = x
Step-by-step explanation:
for this we have to think that the people who moved left, so they have to subtract
lake residents are 154,226
then we would have to subtract those who moved
that we calculate them as 14% of residents
0.14*154,226
then we finally have
154,226 - (154,226 * 104) = x
Cost of visit per month is $414/12 = $34.5
Cost of individual visit per month = $34.5/8 = $4.3125
