I have this problem and not sure which formula to use.

Would this be the Binomial formula? If so how do I go about performing on this equation.

Cheers

Calculate 1 - Pr(no errors). Assuming independence, Pr(no errors) is straightforward.

To calculate the other stuff, substitute the data into the forumulas you've been undoubtedly been given. (If you need more help, please show what you've done and where you get stuck). - September 4th 2009, 12:13 AMabzstar111
Thankyou for your reply mr fantastic.

for part (a) I did this,

p(1) + p(2) + p(3) + p(4) =0.5439

I dont understand part (b) at all. Is it a formula I use?
