Answer:
7 percent
Step-by-step explanation:
We have the following information from the question:
The probability that a student chooses art as an elective is 15 percent:
The probability that a student chooses art or drama is 20 percent:
The probability that a student chooses both art and drama is 2 percent:
Recall that:
We plug in the various probabilities to get:
Hence the probability that a student chooses drama as an elective is 7 percent
A and B are equal to 27^-1
The answer is B. 10 9/12 + 2 1/12= 12 10/12. 12÷2=6 10÷2=5 making the answer 12 5/6
Answer:
x^2-5x+6=0
Step-by-step explanation:
Surface Area of a Sphere = 4π(d/2)²
Let the smaller sphere's diameter be just a sample of 4 units in diameter and let the large spheres diameter be 4 times that of the smaller sphere.
Small Sphere: 4π(4/2)² = 16π units²
Large Sphere: 4π(16/2)² = 256π units²
256π / 16π = 16 times
The large sphere has a surface area 16 times that of the smaller one.
