The probability of two events A and B happening simultaneously is 0.15. The probability of only event A happening is 0.30. Find the probability of event B happening, if event A had already happened.

2/5

Step-by-step explanation:

both A and B is o.15

both Aand B not happening is 0.85

the probablity of only A is 0.30

not hsppening is 0.70

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
