The set of all possible outcomes in an experiment is describe by the . the of two events a and b is the event in which both a and b occur. two events are said to be if they can not occur at the same time.

universal set.,  intersection of two events,disjoint

Step-by-step explanation:

According to set theory, the set of all possible outcomes comprise every think possible and hence called universal set.

Similarly when two events occur simultaneously we say it is the intersection of two events.

If two events cannot occur at the same time then they are called disjoint events

The set of all possible outcomes in an experiment is describe by the universal set .

The __intersection of two event of two events A and B is the event in which both A and B occur.

Two events are said to be __disjoint if they can not occur at the same time.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
