A statistics class conducts a chance experiment in which they observe students who buy a snack at the school vending machines. The type of snack (liquid or solid) is noted, as well as the number of calories from fat in the snack (less than 25, 25 to 75, or more than 75). Define L to be the event the item is liquid and B the event that the item has 75 or fewer calories of fat. How many outcomes are in the union of L and B?

5 possible outcomes

Step-by-step explanation:

The possible outcomes of the event L,  the item is liquid, are:

L= {liquid, less than 25; liquid, 25 to 75; liquid, more than 75}

The possible outcomes of the event B, the item has 75 or fewer calories of fat, are:

B= {liquid, less than 25; liquid, 25 to 75; solid, less than 25; solid, 25 to 75}

The possible outcomes for the union of L and B (L or B) are:

L or B = {liquid, less than 25; liquid, 25 to 75; liquid, more than 75; solid, less than 25; solid, 25 to 75}

Therefore, there are 5 possible outcomes in the union of L and B.

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
