This can be done from the table or calculator
I like the table.
Fewer than 4 means 0,1,2,3 and the probability is 0.355
exclusive of 4 and 9 means 5,6,7,8, and that probability is 0.411
It can also be done by
0: .7^14
1:14*.3*.7^13
2: 14C2*.3^2*.7^12, etc., but this is more extensive for this type of problem.
