Construct the transition matrix that represents the data.A new anti-gravity commuter train has been installed. It is expected that each week 90% of the riders who used the existing system will continue to do so. Of those who traveled by car, 5% will begin to use the new anti-gravity train. Use this information to write the transition matrix that describes this process. T C
