The rule for conditional probability states that
![P(A|B) = \dfrac{P(A\cap B)}{P(B)}](https://tex.z-dn.net/?f=%20P%28A%7CB%29%20%3D%20%5Cdfrac%7BP%28A%5Ccap%20B%29%7D%7BP%28B%29%7D%20)
Since we're given both numerator and denominator, we only need to plug the values in:
![P(A|B) = \dfrac{\frac{4}{7}}{\frac{7}{8}} = \dfrac{4}{7}\cdot \dfrac{8}{7} = \dfrac{32}{49}](https://tex.z-dn.net/?f=%20P%28A%7CB%29%20%3D%20%5Cdfrac%7B%5Cfrac%7B4%7D%7B7%7D%7D%7B%5Cfrac%7B7%7D%7B8%7D%7D%20%3D%20%5Cdfrac%7B4%7D%7B7%7D%5Ccdot%20%5Cdfrac%7B8%7D%7B7%7D%20%3D%20%5Cdfrac%7B32%7D%7B49%7D%20)
This is simple mathematics. 37 - 25 = 12
She travelled 12 feet beneath sea level.
Answer:
Michael: 24
Junior: 8
Step-by-step explanation:
8 is a multiple of 24, meaning if you ate 1/3 of 24 you get 16, which is doubled 8.
Answer:
0.14
Step-by-step explanation:
Here, we want to find the probability that a student earns the grade of A
Mathematically, we have this as the frequency of A divided by the sum of all frequencies
From the question, the sum of all frequencies will be (5 + 10 + 15+ 3 +2) = 35
Now we place the frequency of A over this
This gives;
5/35 = 1/7 = 0.14
