Consider a binomial experiment with n = 20 and p = .70.

if you calculate the binomial probabilities manually, make sure to carry at least 4 decimal digits in your calculations.

a) compute f(12) (to 4 decimals).
b) compute f(16) (to 4 decimals).
c) compute p(x 16) (to 4 decimals).
d) compute p(x 15) (to 4 decimals).
e) compute e(x). 14
f) compute var(x) (to 1 decimal) and (to 2 decimals).
var(x)
o

Step-by-step explanation:

Given that X is binomial n=20: p=0.70

a) Compute f(12) (to 4 decimals).

=

b) Compute f(16) (to 4 decimals).

=

c) Compute P(x <16) (to 4 decimals).

=

d) Compute P(x <15) (to 4 decimals).

=

e) Compute E(x). =np = 14

f) Compute Var(x) (to 1 decimal) and (to 2 decimals).

Var(x)=npq=4.2

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

probability for j is 1/4

while

a is 1/6
