Homework Answers

Answer #1

X : number of people ride the vomitron but do not vomit afterwords.

X ~ bin (n,p)

where, n =7

p = probability of not vomiting after riding = (1-0.4) = 0.6

q = 40% = 0.4

the pmf of the distribution be:-

If 7 people ride the Vomitron,the probability that more than 6 do not vomit afterwards is:-
