A jar contains 7 blue cubes, 4 blue spheres, 5 green cubes, and 6 green sphers. If you select an object at random, what is the probability that the object is green or a cube?
To find the probability that the object is green or a cube, we need to find the total number of green objects, the total number of cube objects, and the total number of objects in the jar.
Total number of green objects: 5 green cubes + 6 green spheres = 11 green objects
Total number of cube objects: 7 blue cubes + 5 green cubes = 12 cube objects
Total number of objects in the jar: 7 blue cubes + 4 blue spheres + 5 green cubes + 6 green spheres = 22 objects
Now, the probability of selecting a green or a cube object is given by:
(11 green objects + 12 cube objects) / 22 total objects = 23 / 22
Therefore, the probability of selecting a green or a cube object is 23/22 or approximately 1.05.
