There are 6 glasses of natural fruit juices, 7 glasses of soft drinks, and 4 glasses of milk shakes served at a get-together. savio chooses 2 glasses in succession without replacement. find the probability that he selects a glass of natural fruit juice, then a milk shake.

Step-by-step explanation:

In Statistics, the AND function, is simplified, by multiplying the probability of the two events with one another:

The first function is the probability of picking a glass of fruit juice from the total number of glasses. There is a total of 17 glasses, and 6 of them are fruit juice:

After taking a fruit juice, there are only 16 glasses left, of which 4 are milkshakes:

Therefore:

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
