Stephen, could you do the workout on the math once again - this way I can go back and re-study how you are coming to these conclusions. I will definitely add a tip for the help.
Expert:  Steve replied 5 years ago.

The answer is found by summing the probabilities that either 0, 1, 2 or 3 do support spending.

 

This is the same as the previous question, you just sum up 4 seperate probabilities

 

 

6 choose 0 x 0.25^0 x 0.75^6 + 6 choose 1 x 0.25^1 x 0.75^5 + 6 choose 2 x 0.25^2 x 0.75^4 + 6 choose 3 x 0.25^3 x 0.75^3

 

Please do not forget to press accept, and tip as promised.

 

thanks
