Of 60 diners in a restaurant, 15 ordered the fish of the day and 7 are wearing a tie. Of the diners who ordered fish, 2 are wearing a tie. Which is the probability that one of the diners ordered the fish or is wearing a tie? A. 0.37
B. 0.03
C. 0.5
D. 0.33

D. 0.33

Step-by-step explanation:

To solve this question, we use Venn probabilities.

I am going to say that:

Event A: Ordered fish of the day.

Event B: Are wearing a tie.

Of 60 diners in a restaurant, 15 ordered the fish of the day

This means that

7 are wearing a tie.

This means that

Of the diners who ordered fish, 2 are wearing a tie.

This means that

Which is the probability that one of the diners ordered the fish or is wearing a tie?

This is:

Replacing with the values we have:

The correct answer is given by option d.

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.
