Answer:
The probability of spinning red with the spinner or rolling an odd number with the die is 
Explanation:
Given that,
Total color in spinner = 4
Let the area of four parts is equal in the spinner.
We need to calculate the probability of spinning red
Using formula of probability

Put the value into the formula

We need to calculate the probability of odd number of the die
Using formula of probability

Put the value into the formula


We need to calculate the probability of spinning red with the spinner or rolling an odd number with the die
Using formula of probability of two events which is independent

Put the value into the formula


Hence, The probability of spinning red with the spinner or rolling an odd number with the die is 
Answer:
the crust is solid because the particles are tightly packed and moves very little. the mantle is a liquid because the particles are more spread apart and have more movement.
Explanation:
i already explained it :)
1 or 8 i believe would be the answer
Explanation:
It is known that number of moles of a substance equal to mass divided by its molar mass.
Mathematically, No. of moles = 
It is given that no. of oles present are 27.2 mol and molar mass of N is 14 g/mol.
Therefore, calculate mass of N as follows.
No. of moles = 
27.2 mol = 
mass = 380.8 g
Thus, we can conclude that mass of N is 380.8 g.
