A jar contains 7 blue cubes, 4 blue spheres, 5 green cubes, and 6 green spheres. If you select an object at random, what is the probability that the object is green or a cube? A. 23/22 B. 5/22 C. 9/11 D. 4

Do you know how?

OpenStudy (anonymous):

I did 11/22 + 12/22 = 23/22

OpenStudy (anonymous):

count

OpenStudy (anonymous):

and that answer cannot be right because a probability is never bigger than one

OpenStudy (anonymous):

there are 22 in total so that will be your denominator unless you need to reduce the fraction

OpenStudy (anonymous):

5 green cubes + 5 green spheres/22 then 7 blue cubes + 5 green cubes/22 It said what's the probability of green or cube.

OpenStudy (anonymous):

don't count the green cubes twice

OpenStudy (anonymous):

Oh okay. Thanks
