Answer:
2 5/6
Step-by-step explanation:
WE CHANGE 3 1/2 INTO IMPROPER FRACTION WHICH IS 7/2
7/2-2/3=2 5/6
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.
