P(getting someone who tests negative / he or she did not have disease)

= Count(getting someone who tests negative and he or she did not have disease) / count(he or she did not have disease)

= 125 / (125+31)

= 0.801

6 of 30

P(getting 4 correct out of 60) = 4/60 = 1/15

P(single correct between 1 to 22 in separate draw) = 1/22

P(winning jackpot) = P(getting 4 correct out of 60) * P(single correct between 1 to 22 in separate draw)

= 1/15* 1/22

= 1/330
