Abox contains 3 blue marbles, 5 red marbles, and 4 white marbles. if one marble is drawn at random, find p(not red inot white). enter your answer in decimal form rounded to two decimal places.

p(a|b)= p(a and b)

p(b)

Step-by-step explanation:

p(b)=3/12 = 0.25

p(r)=5/12 = 0.42

p(w)=4/12 = 0.33

p(¬r) = 1-0.42 = 0.58

p(¬w)= 1-p(w) = 0.67

P(not red Inot white)= 0.58/0.67=0.87

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
