WEEK 4 LAB LECTURE For the first one, x ≥ 1, you would add all of

the probabilities from 1 through 10 for 2/5 or calculate 1 – P(0)

WEEK 4 LAB LECTURE For the second one, x > 1, you would add

all of the probabilities from 2 through 10 for 2/5 or calculate 1 – (P(0)+P(1))

WEEK 4 LAB LECTURE For the third one, 4<x ≤ 7, you would add

all of the probabilities from 5 through 7

WEEK 4 LAB LECTURE For the last one, x < 4 OR x ≥ 7, you would add all of

the probabilities from 0 through 3 AND all probabilities from 7 through 10 (OR YOU COULD SAY 1 – THOSE NOT INCLUDED)


Mean = 10 (2/5) = 4 Std Dev = Sq Root (10)(2/5)(3/5) = 1.549


USE DEFINITION OF BINOMIAL DISTRIBUTION…..
