A system contains two components, A and B. The system will function only if both components function. The probability that A functions is 0.98, the probability that B functions is 0.95, and the probability that either A or B functions is 0.99. What is the probability that the system functions?

Probability that the system functions = 0.94 .

Step-by-step explanation:

We are provided that a system contains two components A and B. The system will function only if both components function means system will not function if only one component functions.

Also, Probability that A functions, P(A) = 0.98

         Probability that B functions, P(A) = 0.95

         Probability that either A or B functions, P(A B) = 0.99

Now we have to calculate the Probability that the system functions which mean Probability that both system will function, P(A B);

   Since, P(A B) = P(A) + P(B) - P(A B)

                 0.99   = 0.98 + 0.95 - P(A B)

Therefore, Probability that the system functions, P(A B) = 0.94 .

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
