HELP PLZZ Which of the following actions will always be independent events?

selecting two cards from a standard deck, one at a time

selecting two marbles from a bag, one at a time

flipping two coins, one at a time

picking two letter tiles from a hat, one at a time

The third one i think. They are separate.

Step-by-step explanation:

C: Flipping two coins, one at a time.

Explanation:

A, B, and D all include all different objects like Cards, Marbles, and Letter tiles. These are all items of quantity. Flipping two coins is independent because they are singular objects (that aren't inside of a bag or a hat).

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
