A pet store has 14 puppies, including 5 poodles, 5 terriers, and 4 retrievers. If Rebecka selects one puppy at random, the pet store replaces the puppy with a puppy of the same breed, then Aaron chooses a puppy at random. Find the probability that they both select a poodle.

25/196 = 0.128

Step-by-step explanation:

There are a total of 14 puppies, 5 of which are poodles.

The probability that Rebecka selects a poodle is 5/14.

Since the poodle is replaced, the probability that Aaron selects a poodle is also 5/14.

So the probability of both is (5/14) (5/14) = 25/196 = 0.128.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

yes
