Question

calculate the probability of selecting a random.
1. the winning horse in a race in which 10 horses are running
2. the winning horses in both the first and second races if there are 10 horses in each races​

Answer 1

PROBABILITY= Number of possible outcomes for the event/Total number of possible outcomes.

1) Given:- The winning horse in a race in which 10 horses are running and randomly a horse wins.

Let, A be the event (horse picked randomly wins).

Total number of possible outcomes=10

Number of possible outcomes of event (A) = 1

So, the probability of event (A) =1/10

2)Given:- The winning horses in both the first and second races if there are 10 horses in each race

Let, H be the event (horses picked randomly win).

Total number of possible outcomes = 10+10=20

Number of possible outcomes of event (H) = 2

So, the probability of event (H) = 2/20=1/10

Therefore, from both the probabilities we get to know that both events have equally likely outcomes.
