What is the probability of the following. (a) An event A that is certain to occur?
(b) An event B that is impossible?
Enter an exact number

(a) The probability of an event A that is certain to occur is 1.

(b) The probability of an event B that is impossible is 0.

Step-by-step explanation:

The probability of an event can be described as the chance that the event will occur.

The probability that an event will occur is between 0 and 1.

Based on the above, we can answer as follows:

(a) What is the probability of an event A that is certain to occur?

The probability of an event A that is certain to occur is 1.

(b) What is the probability of an event B that is impossible?

The probability of an event B that is impossible is 0.

the answer is c

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)
