Among 806 people asked which is there favorite seat on a plane, 492 chose the window seat, 8 chose the middle seat, and 306 chose the aisle seat, then
![P(\text{Window seat})=\dfrac{492}{806}=\dfrac{246}{403}\\ \\P(\text{Middle seat})=\dfrac{8}{806}=\dfrac{4}{403}\\ \\P(\text{Aisle seat})=\dfrac{306}{806}=\dfrac{153}{403}](https://tex.z-dn.net/?f=P%28%5Ctext%7BWindow%20seat%7D%29%3D%5Cdfrac%7B492%7D%7B806%7D%3D%5Cdfrac%7B246%7D%7B403%7D%5C%5C%20%5C%5CP%28%5Ctext%7BMiddle%20seat%7D%29%3D%5Cdfrac%7B8%7D%7B806%7D%3D%5Cdfrac%7B4%7D%7B403%7D%5C%5C%20%5C%5CP%28%5Ctext%7BAisle%20seat%7D%29%3D%5Cdfrac%7B306%7D%7B806%7D%3D%5Cdfrac%7B153%7D%7B403%7D)
a) One randomly selected person preferes aisle seat with probability
![\dfrac{153}{403}](https://tex.z-dn.net/?f=%5Cdfrac%7B153%7D%7B403%7D)
b) Two randomly selected people both prefer aisle seat (with replacement) is
![\dfrac{306}{806}\cdot \dfrac{306}{806}=\dfrac{153}{403}\cdot \dfrac{153}{403}=\dfrac{23,409}{162,409}](https://tex.z-dn.net/?f=%5Cdfrac%7B306%7D%7B806%7D%5Ccdot%20%5Cdfrac%7B306%7D%7B806%7D%3D%5Cdfrac%7B153%7D%7B403%7D%5Ccdot%20%5Cdfrac%7B153%7D%7B403%7D%3D%5Cdfrac%7B23%2C409%7D%7B162%2C409%7D)
