In a pet store, there are 6 puppies, 9 kittens, 4 gerbils and 7 parakeets. If a pet is chosen at random, what is the probability of choosing a puppy or a parakeet?
Answers
Answer:
Step-by-step explanation:
Total = 26
probability of puppy = 6\26 = 3\13
probability of parakeet = 7\26
More probality of two is of parakeet.
Given,
Total number of pets = 26
Number of puppies = 6
Number of kittens = 9
Number of parakeets = 7
To find,
We have to find the probability of choosing a puppy or a parakeet.
Solution,
The probability of choosing a puppy or a parakeet is 1/2.
We can simply find the probability of choosing a puppy or a parakeet using the formula of probability.
Probability = Favorable cases / Total number of cases
P ( of getting a puppy) = 6/26
P ( of getting a parakeet) = 7/26
P ( of getting a puppy or a parakeet) = 6/26 + 7/26
= 13/26
= 1/2
Hence, the probability of choosing a puppy or a parakeet is 1/2.
