Hi, i'm david and i'm here to help you answer your question.
00:03
Now let me bring up your question here.
00:06
In this question, i want to play a game on the spinner.
00:10
And we have on the spinner, we have four labels, a, b, c and d.
00:16
And we have to pay $2 for the game each time.
00:16
And d and we have to pay two dollars for the game each time and if you plan on the c you will play you will win a quarter if you plan on the a you will win nine and then otherwise we win nothing so therefore let me call the x it will be the net again and i try to write down this one here this will be the outcomes and this will be the volume the x the outcome it can be the a and then b c and then the d now when you get the a and then you have to pay two dollars so will be minus two but you win a quarter it means that you plus the 0 .25 if you plan on the oh sorry you plan on a then you will blur you will win nine dollars so this one will be plus nine here.
01:31
Plus nine.
01:32
If you land on the b and the d, you will know things means that you will lost $2 for the bat.
01:40
And if you land on the c, you have to pay $2, but on return you have to win the 0 .25, which is the quarter...
