The probability of an event is 3/10 . What are the odds of the same event?
kozerog [31]

Answer:

D. \frac{3}{7}

Step-by-step explanation:

We have been given that the probability of an event is 3/10.  

To find the odds of the same event we will use formula:

\text{Odds of an event}=\frac{\text{Probability of the event}}{\text{1-Probability of the event}}

\text{Odds of the event}=\frac{\frac{3}{10}}{1-\frac{3}{10}}

\text{Odds of the event}=\frac{\frac{3}{10}}{\frac{1*10}{10}-\frac{3}{10}}

\text{Odds of the event}=\frac{\frac{3}{10}}{\frac{10-3}{10}}

\text{Odds of the event}=\frac{\frac{3}{10}}{\frac{7}{10}}

Dividing a fraction with another fraction is same as multiplying the 1st fraction by the reciprocal of second fraction.

\text{Odds of the event}=\frac{3}{10}\times \frac{10}{7}

\text{Odds of the event}=\frac{3}{7}

Therefore, the odds of the same event is \frac{3}{7} and option D is the correct choice.
