Hey Guys can someone help me with two questions on the OCR.

First one is in June 2010 q8iib) I dont understand why you multiply by 0.7^5, just doesn't make sense

Next Question

Jun 2009 Link to Paper:http://www.ocr.org.uk/Images/57773-q...atistics-1.pdf

How do we do q9, I dont seem to be getting 24, from the mark scheme we make it so it equals 0.05 apparently, could someone explain to me why this is

For June 2010 q8iib - for there to be more than 5 interviews it means that in the first 5 there was either just 1 viewer of West street or no viewers of West street, calculate these probabilities.
