Decide whether the two events are disjoint and tell why or why not:
• randomly choosing a scarf that is blue
• randomly choosing a scarf that is frayed

A: Not disjoint, because the events cannot occur at the same time.

B: Disjoint, because the events cannot occur at the same time.

C: Disjoint, because the events can occur at the same time.

D: Not disjoint, because the events can occur at the same time.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
