F5 Distribution

Then F5 Binomial Dist

For point dist select Bpd

Select Data: Variable

For P(X=3), n = 12

p = 0.15For P(X=3) = 0.1720

For cumulative select Bcd

For P(X<3),

n = 10

p = 0.2

Use P(x 2)

P(x 2) 0.6778 P(x 3) 0.6778

For Cumulative Ncd

For Inverse InvN

Example std normal

P(0<x<1.736)

Mean: 0, sd = 1 (Select Ncd)

P(0<x<1.736)= 0.4587
