This is the question I need help with:

"The probability that I will need to fill up with petrol each time I borrow the car is 0.32. What is the probability that out of the next 5 times I borrow the car, it will need filling up with petrol at least once?"

Working would be nice too :)

Can you figure out the probability that you'll never have to fill it up in those 5 times?
