In one region, 77% of people speak English only when they are at home, 12% speak only French, 10% speak only another language, and the remainder speak more than one language. Suppose that you are conducting a poll by calling people in this region at random. For your first three calls, find the following probabilities.
a) What is the probability that you talk to only people that speak only English at home?
b) What is the probability that you talk to no people that speak only French at home?
c) What is the probability that you talk to at least one person who speaks only a different language at home?
a) The probability is

mental cunning

explanation:

he is often referred to as a man of twists and turns

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.
