Answer:

Please double check what you've written

Step-by-step explanation:

Probability is, by definition, a number between 0 and 1, which can be expressed as a fraction or a percentage. For example, the odds of getting heads if you throw a fair coin are 50%, or ½. The odds of not getting heads are 1-½=½.

If the probability of something happening is 1, it means that that thing will happen for sure. Likewise, if the probability of an event is 0, it means that the event will never happen.

You can therefore easily understand that it doesn't make sense to have a probability greater than 1, I would thus advise you to read the question more carefully.

The answer is 3/10 , Option D

What is Probability ?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.

The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Probability Formula = f/n

where,

f is the number of times an event occurs

n is the total number of trials

Odds are a/b ;

probability is a/(a+b)

The odds of event happening is 7/3

Probability is 7/(7+3)=0.7 of the event happening.

So the probability of it not happening is 1–0.7= 0.3.

probability of it not happening is 3/10

Therefore Option D is the correct answer.
