thats the answer just look at the picture :)
for the work
2,880 people
Week 1: 3,000 cases
Week 2: 0.4 * 3,000 = 1,200. 1,200 + 3,000 = 4,200
Week 3: 0.4 * 4,200 = 1,680. 1,680 + 4,200 = 5,880
5,880 - 3,000 = 2,880
I got 70
Combination=n!/((n-r)!r!)
=8!/((8-4)!*4!)
=8*7*6*5*4!/(4!*4!)
=8*7*6*5/(4*3*2)
=70 ways
