explain the difference between independent and dependent events AND how I can tell the difference in a word problem.

Example: Suppose you have a bag of marbles, there are 4 white, 4 zebra striped, and 2 black. You take out a marble without looking, you do not replace it and then you take out another marble. What is the p

Answers

Answer 1

Answer:

The difference between the two is that in a dependent event an action will affect the ultimate outcome, but in an independent event an action won't affect the ultimate outcome. A way to tell is if the total number of the "item" at hand will be affected by the action the question is saying. In the case of the example given, that is a dependent event because the total of marbles you started with is changed due to you not replacing the one you first took. Therefore the probability is now different.

PLEASE LOOK AT EXAMPLE AND THEN ANSWER QUESTION ONE I DON'T REALLY KNOW NUMERICAL EXPRESSION STUFF PLEASE HELP!! I WILL GIVE BRAINLIST!

Answers

Answer:

(cant see question one, post as comment if you can pls)

Step-by-step explanation:

ok, first lets understand what numeral means,

Numeral is anything to do with numbers, so a numeral expression is an expression that contains mostly or all numbers, for example;

3 plus 5 minus 2 equals-

would be converted into a numeral expression

3 + 5 - 2 =

now, lets look into what a quotient is

a quotient is the product or answer to a division problem, say we did...

12 / 4 = a ( '/' or slash is used as a division sign when typing on a keyboard)

a would be the quotient, just like 12 is the numerator (the number you start with) and 4 is the divisor (the amount of groups your dividing the numerator into)

NOTE: the quotient is NOT to be confused with the sum of two numbers, the sum is almost the same, but it is instead the product of an addition problem

now for the parenthesis ' ( ) ', a parenthesis in a numeral expression just tells you to solve that part of the problem first, even before multiplication when following order of operations, heres a problem to show you what i mean

10 * 2 + (5 - 3) =

normally we would multiply, then add, then subtract, but with the parenthesis we need to do whats inside them first, so for this we would subtract in the parenthesis, then we would solve the rest of the problem as normal

i hope this makes sence, ill update the answer when i get more info, comment any questions you have about this

take care and good luck :>
