You need to find out how many ways to arrange ten 1’s and eight 0’s in such a way that no two 0’s are adjacent.
Please help! I'm not really sure how to start solving this problem. A parking lot has 18 spaces in a row. 10 cars arrive, each of which requires one parking space and their drivers choose their spaces at random from among the available spaces. Auntie Em then arrives in her SUV, which requires 2 adjacent spaces. What is the probability that she is able to park?
Hello, sweeetcaroline!
Am I reading the problem correctly?

We are parking ten normal cars: .
. . and one SUV: .
After the ten cars are parked randomly, what is the probabiity
. . that there is at least a pair of adjacent empty spaces?
