Hi
Poisson Distribution:
p%28x%29+=+%28mu%5Ex%2Fx%21%29%2Ae%5E%28-mu%29
a. p%280%29+=+%28.002%5E0%2F0%21%29%2Ae%5E%28-.002%29 = .998

Or Using TI or similarly an inexpensive calculator like a Casio fx-115 ES plus 
P(7) = poissonpdf(mean, x-value) = poissonpdf(.002, 0) = .998

b. P(x ≥ 2) = 1 - P( x ≤ 1) = 1 - P(0) + P(1) = 1 - .998 + .001996  = 0
or
1 - poissoncdf(.002, 1)  = 1 -0.9999980027 = basically 0
Wish You the Best in your Studies.
