You decide you are going to buy a lottery ticket if the expected earnings are larger than the ticket price. Tickets
cost $3, and you get $900 if you win. The odds of winning
1
are 1 in 400, meaning that you will win with probability
400
What is the expected earnings in this lottery, and should you
buy a ticket?

answer: 5

step-by-step explanation:

since, the range is the difference between the lowest and highest values of the given sample space.

and, here the sample space = { 3, 1, 0, 4, 1, 4, 2, 3, 0, 5, 0, 1, 1, 2, 0, 4, 1,4, 4 ,2 ,3 ,2 ,0 ,1 ,4 }

here, the highest value of the given sample = 5

and, the lowest value = 0

therefore, the range of the sample space = 5 - 0 = 5

it goes right

i believe b is the answer
