Question

I need help with this really bad.
At West Middle School, 30% of students have a dog, 20% of students have a cat, 10% of students have another kind of pet, and 40% of students have no pets.
a) Explain how you can use a random-number table to find the experimental probability that in a group of 5 students, at least 2 will have a dog.
b) Use your model from part a and the table below to find the experimental probability that in a group of 5 students, at least 2 will have a dog.
65926 31459 31986 65809 80462
27387 39075 46738 21986 59837
91384 10987 26491 68498 98796
32596 26448 31235 63256 53121

Answer 1

well, you could say that
0-2 represents a dog
3-4 represents a cat
5 represents other pet
6-9 represents no pet

then, sample groups of 5 digits as above, counting what percent contain two or more 0,1,2 digits
