Step-by-step explanation:
Answer: ![\dfrac{16}{49}](https://tex.z-dn.net/?f=%5Cdfrac%7B16%7D%7B49%7D)
Step-by-step explanation:
Given: A bag contains 4 sour-apple candies and 3 watermelon candies.
Total candies = 4+3 = 7
If replacement of candy is done, then the probability of getting sour apple will be the same and independent each time .
Probability of selecting sour apple candy= ![\dfrac{\text{Number of sour apple candy}}{\text{Total}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BNumber%20of%20sour%20apple%20candy%7D%7D%7B%5Ctext%7BTotal%7D%7D)
![=\dfrac47](https://tex.z-dn.net/?f=%3D%5Cdfrac47)
Now , the probability that both pieces of candy chosen will be sour -apple =![\dfrac47\times\dfrac{4}{7}=\dfrac{16}{49}](https://tex.z-dn.net/?f=%5Cdfrac47%5Ctimes%5Cdfrac%7B4%7D%7B7%7D%3D%5Cdfrac%7B16%7D%7B49%7D)
hence, required probability = ![\dfrac{16}{49}](https://tex.z-dn.net/?f=%5Cdfrac%7B16%7D%7B49%7D)
21g=84
g=84/21
g=4
The answer is B
