A bag contains five red marbles, four blue marbles, and four yellow marbles. You randomly pick a marble. What is the probability that the marble is red or blue?

n(s)= 5+4+4=13

n(e)= red + blue

=5+4

=9

so, p(e) = n(e)/n(s)

p(e)= 9/13

=0.69

it's your answer

it will help.

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

step-by-step explanation:

hope this !

a)(x-2)^2+(y-1)^2=9
