Answer:
$0.36
Explanation:
Expected value of the lottery ticket = (p1 x a1) + (p2 x a2) + (p3 x a3) + (p4 x a4)
p1 = probability of winning $1 = 1/5 = 0.2
a1 = $1
p2 = probability of winning $5 = 1/100 = 0.01
a2 = $5
p3 = probability of winning $1000 = 1/100,000 = 0.00001
a3 = $1000
p4 = probability of winning $1 million = 1/10,000,000 = 0.0000001
a4 = $1 million
(0.2 x 1) + (0.01 x 5) + (0.00001 x 1000) + (1,000,000 x 0.00001) = $0.36
