Answer:

d=\sqrt(x2-x1)^{2}  + (y2-y1)^{2}

x1= -2

x2=2

y1= 2

y2= -1

2-

2- solve the equation:

d=\sqrt\(2-(-2))^{2}  + ((-1)-2)^{2}

d= \sqrt(4)^{2}        + (-3)^{2}

= \sqrt16        + 9

= \sqrt25

The probability that if Air-USA books 24 persons, not enough seats will be available

= P(X=23)+P(x=24)

= 0.1315

B. no, it is not low enough

-------------------------------

The prob we got is >10% also
