Question 1149908
This is a binomial with p=0.3 and n=6
probability of 0 is 0.7^6=0.1176
of 1 is 6* 0.7^5*0.3=0.3025, the 6 from 6 different ways it can happen
of 2 is 6C2*0.7^4*.3^2=0.3241
of 3 is 6C3*0.7^3*0.3^3=0.1852
of 4 is 6C4*0.7^2*0.3^4=0.0595
of 5 is 6*0.7*0.3^5=0.0102
of 6 is .3^6=0.0007
use this for the answers
a. is 4,5,6 or 0.0704
b. at least 2 is 1- 0 and 1 or 1-0.4201 or 0.5799
c. at most 3 is probability 0,1,2,3 or the complement of a or 0.9296.
d. less than 5 is 1- 5 and 6 or 1-0.0109 or 0.9891
