A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P ( red or blue)

Step-by-step explanation:

To find the combined probability we will write as a fraction with the number of occurrences for the specified conditions.

Here, we have 16 marbles total (as 6 + 6 + 4 = 16) and we want to find the probabiliy of choosing either a red or blue marble out of the 16. There are 10 marbles that are either red or blue (as 16 - 6 = 10) so the fraction would be 10/16. However, we still need to get this simplest form.

As we cannot simplify 5/8 any further, this is the final answer.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
