80% of companies ship their products by truck. 50% of companies ship their product by rail. 60% of companies ship by either truck or rail. What is the probability that a company ships by truck and rail

0.7 = 70% probability that a company ships by truck and rail.

Step-by-step explanation:

We solve this question, using Venn probabilities.

I am going to say that:

Event A: Ship by truck.

Event B: Ship by rail.

80% of companies ship their products by truck.

This means that

50% of companies ship their product by rail.

This means that

60% of companies ship by either truck or rail.

This means that

What is the probability that a company ships by truck and rail?

This is , given by:

Using the given values:

0.7 = 70% probability that a company ships by truck and rail.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
