The probability of an event is 3/10. What are the odds of the same event?
a. 10/13
b. 3/13
c. 7/10
d. 3/7
To calculate the odds of an event, we can use the formula Odds = Probability of the event / (1 - Probability of the event).
In this case, the probability of the event is 3/10.
Odds = 3/10 / (1 - 3/10)
= 3/10 / (7/10)
= 3/10 * 10/7
= 3/7
Therefore, the odds of the event are 3/7.
The correct option is d. 3/7.
