(1) 0.016597

(2) 0.040978

(3) 0.080277

(4) 0.341909

Step-by-step explanation:

1) probability of one or more catastrophes in the next: two missions = 1-P (no catastrophes) = 1 - (119/120) 2 = 0.016597

2) probability of one or more catastrophes in the next five missions = 1 - (119/120) 5 = 0.040978

3) probability of one or more catastrophes in the next ten missions = 1 - (119/120) 10 = 0.080277

4) probability of one or more catastrophes in the next fifty missions = 1 - (119/120) 50 = 0.341909
