Question 1083991
Probability of greater than 4, or 5 or more, is 0.170 from the table.
Do probability 5 which from the calculator is 2nd VARS 0, binompdf
input (20,.15,5) and that is the probability of exactly 5
0.1028
now do 6 (20,.15,6)=0.0454
now 7: 0.0160
and 8: 0.0046
and 9: 0.0011
and 10: 0.0002
The rest are insignificant
Add those: 0.1701
Alternatively do 0,1,2,3,4 and subtract from 1.
Using the table for 20 and say 0.2, one can look at the specific probability of a number and a cumulative probability for all the numbers up to and including that one.  If one works on the calculator and looks at the table, this can be clarified.
