How to calculate these particular values in this experiment?

40 Views Asked by At

I am running a statistics experiment where I need to calculate certain values. However, this is where I am having difficulty. Here is how the experiment works:

  • Two Individuals Participate

  • There is a spinner with 6 labeled tiles[1-6] and a regular die

  • A player spins the spinner, and throws the die

  • If the value obtained from adding the sums of the die's value and number on the spinner is 8 or greater, than the individual gets $10, otherwise nothing

  • The first individual to get $80 in total wins

Calculations

From what I have obtained so far, this is all I know:

$$P(obtaining $10) = 5/11$$ Number of trials to get 80 dollars[using geometric distribution] = $$(5/11)(1-(5/11))^7 = 0.006530$$

However, this just gives me a number between 0 and 1 - how can I turn this into the number of trials needed to obtain $80?

I'm trying to create a probability distribution along with find the the expected value and standard deviation - however, I need some assistance on where to start.
