true or false? .to find the number of outcomes of disjoint sets, add the number of outcomes for each event.

True

Step-by-step explanation:

When two events are disjoints then both events does not occur at the same time.

The intersection of both events is 0

Tossing a coin and getting a tail or head are the two disjoint events

To find the number of outcomes of disjoint sets, we add the number of each event like we add the number of outcomes of getting head and tail .

So, its true

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
