First we have to calculate the probability that a person wins a lottery with just one ticket :
The number of the combinations:
59 C 5 = ( 59 * 58 * 57 * 56 * 55 ) / ( 5 * 4 * 3 * 2 * 1 ) = 5,006,386
So the probability to win is:
1 : 5,006,386 = 0.0000002
$1,000,000 - 0.0000002 = $0.2 ( gain )
and if a ticket costs $1:
$1 - $0.2 = $0.8 ( loss )
Answer: D ) - $0.8
