Answer:
32
Step-by-step explanation:
Possible outcomes in a fair sided die 1,2,3,4,5,6 = 6 possible outcomes
Odd numbers = 1,3,5 = 3 odd numbers
Probability of rolling an odd number = 
= 
Total number of rolls = 64
expected number of odd number rolls in 64 roll,
= x 64 = 32
We have events:
- a <span>student stays in the school's dormitory
- </span>a <span>student stays with family
- </span><span>a student receives As
and </span> probabilities:
We want to calculate the probability <span>that the student lives in the school dormitory given he </span><span>receives As so it will be </span>
. From the <span>Bayes' theorem we know that:
The only thing we don't know is
, but we can calculate it using the l</span><span>aw of total probability. There will be:
So our probability:
Answer D.

Hello,
(x+2i)(x-2i)(x-4)=(x²+4)(x-4)=x^3-4x²+4x-16
Answer C
Scientific define mass
In physical science, mass is a measure of the number of atoms in an object combined with the density of those atoms. The mass of an object determines how that object responds to forces such as gravity and friction. The typical unit of measure for mass is kilograms.
