Answer:
Option A)
Step-by-step explanation:
We are given a tree diagram that represents all the students in a high school.
We have to find the probability that the student is left-handed provided if the student is known to be a girl.
Conditional Probability:
Putting the values from the tree diagram:
Thus, 0.1667 is the probability that the student is left-handed provided if the student is known to be a girl.
Answer is A because 300 ÷6=50 so 50 student is left handed it's also same to 1/6.

Hi there!
What we know:
There were 6 cans of dog food Each can contained 48.6 g of protein
To find the total grams of protein that Michael's dog ate, multiply 48.6 g by 6 cans:
48.6 × 6 = 291.6
Therefore, Michael's dog ate 291.6 g of protein altogether.

We will start with 3 x 7 = 21
Multiply the values under the root
Square root 36 = 6 and square root y^4 = y^2
Then multiply 21 by 6y^2
The answer is D
