Question

1. The probability of event equal to zero is called;
(a)Unsure event b)Sure Event Impossible event
(d)Independent event

​

Answer 1

Answer:

Answer: c

Step-by-step explanation:

The probability of an event that cannot be happened or which is impossible is equal to zero.

Answer 2

The probability of event equal to zero is called an (c) Impossible event.

(c) Impossible event- correct option

• Probability is defined as the likelihood that something will happen.
• An impossible event is one that has no possibility of happening.
• Therefore, there is no chance that an impossible event will occur so its probability is zero.
• Hence, this option is correct.

(a) Unsure event- incorrect option

• An unsure event may or may not occur.
• It lies between an impossible even and a sure event.
• So, it's probability is anywhere between 0 to 1.
• Hence, this option is incorrect.

(b) Sure event- incorrect option

• A certain or sure event is one that is guaranteed to occur.
• A sure event's chance of occurring will always be 1.
• For instance, the earth's rotation around the sun is a sure or certain event.
• Hence, this option is incorrect.

(d) Independent event- incorrect option

• Independent events are those whose results or outcome don't depend on any previous results.
• The likelihood of independent occurrences occurring is constant regardless of how many times an experiment has been run.
• A coin toss is an independent event in probability, for instance.
• It's probability maybe anywhere between 0 to 1.
• Hence, this option is incorrect.
