FAN AND MEDAL A spinner is separated into 3 equal pieces, as shown below: A spinner is shown with three colors, red, yellow, and purple, marked on it. The arrow points towards the red color. Mary spins the spinner 6 times. What is the theoretical probability that it stops on the red sector on the last spin? 1 over 36 1 over 9 1 over 3 2 over 3
@chrissyC.
Ok do you have any guesses?
i have no idea
Ok give me one second
|dw:1429377770745:dw| This is how the spinner is looking for the first step
sorry i forgot to put it in
Mk so yea it looks similar to the one i've done . Now pretend that your mouse or your finger is the arrow and spin it 6 times around the circle
okay and what do i then do?
which color did you land on
purple
|dw:1429378091710:dw|
ok seems like we both landed on purple
So with this information that we have gotten D would be crossed out there is not a chance of 2/3 for red to be picked
okay
also were would we get 36 or 9 from A and B ????
idk
so its 1 over 3?
i would go with C because the circle is split in 3 so every color has the same chance of being picked so each color is 1 to 3--1 to 3---1 to 3 With this information like i said i'd go with C
thanks c:
