In new jersey's pick 4 lottery game, you pay 50 cents to select a sequence of four digits, such as 1332. if you select the same sequence of four digits that are drawn, you win and collect $2788.
1. Find the expected value?

can you select 0 as a lead digit, as in 0345? If so
EV=.50*1/10,000= a tad below nothing.
