BINOMCDF on calculator question

I understand the X is 1-5 but I don't understand what to put in the lowerbound and upperbound of the calculator for

BinomCDF(5,0.5,?,?)

Answer 1

Step-by-step explanation:

For the purpose of filling in the table, the BINOMPDF function is more appropriate. The table is asking for p(x)--not p(n≤x), which is what the CDF function gives you.

If you want to use the binomcdf function, the lower and upper limits should probably be the same: 0,0 or 1,1 or 2,2 and so on up to 5,5.

The binomcdf function on my TI-84 calculator only has the upper limit, so I would need to subtract the previous value to find the table entry for p(x).
