Answer:
0.271 or 27.10%
Step-by-step explanation:
If the present month is January, in 16 months there will be three space shuttles launched (two in June and one in October).
The probability that at least one launch will be delayed is 100% minus the probability that no launch will be delayed:

The probability that at least one of the launches in the next 16 months will be delayed is 0.271 or 27.10%.

The problem cannot be fully solved because you did provide the line on which the line is parallel/ but i can give you the steps on how to solve it. first solve the slope of the parallel line by
m = ( y2 - y1 ) / ( x2 - x1 )
then the slope of that line is equal to slope of line passing pooint ( -1 , 1)
then solve the y intercept of the line using
y = mx + b
where b is the y intercept
then you will have the equation of the line
