Amissile guidance system has seven fail safe components the probability of each failing is 0.30 what is the binomial if exactly five fail

P(x,y) be the general point of the line then:
(x1,y1)=(-9,4)
Equation in point slope form is:
↪m=(y-y1)/(x-x1)
or, -2/3=(y-4)/{x-(-9)}
or, -2/3=(y-4)/(x+9)➡point slope form
or, -2(x+9)=3(y-4)
or, -2x-18=3y-12
or, 2x+3y=-18+12
or, 2x+3y=-6➡standard form of equation
or, 3y=-2x-6
or, y=(-2/3)x-2➡slope intercept form
