## Elementary Statistics (12th Edition)

a)Here we can use the complement rule: P(not blue)=1-P(blue)=1-35%=1-0.35=0.65. b) The probability of having blue eyes are independent, hence we can us the multiplication rule: P(all eyes are blue)=$0.35^4=0.015.$ c) By using the result of b), it is very unlikely to select 4 people randomly and all of their eyes to be blue.
