Probabilities! In order to find the answer you first have find out the total amount of marbles that you have. So:

[7 + 9 + 6] = 22

This number will go into the denominator. 

The next step is to find how how many marbles are not green. To do that you simply add the red marbles and the blue marbles. So:

[7 + 9] = 16

This number will go in the numerator.

The probability of you choosing a marble that is not green is 16/22. You can also simply this and it would be 8/11.

Jose bought a pair of sneakers, a gaming headset and a T-shirt for $77. The headset cost two times
Margarita [4]

Answer:

The cheapest item is T shirt costing $13.

Step-by-step explanation:

Let the cost of T shirt =  $ m

So, the cost of the headset = $ (2m)

and, The cost of Sneakers  = $ ( m + 25)

Total amount spent by Jose = $77

Now, According to the question:

$ m + $ (2m) + $ ( m + 25) = $77

or,  4m + 25 = 77  ⇒  4m = 77 - 25 =  52

or,  m = 52/4 = 13

⇒ The cost of one T- Shirt = m = $ 13

The cost of the headset = (2m)  =  13 x 2  = $ 26

The cost of Sneakers  = $ ( m + 25)  = 13+ 25 = $ 38

As, out of all costs, $13 is the lowest cost

Hence, the cheapest item is T shirt costing $13.
