Question
Each of the whole numbers from 1 to 20 is written on one of 20 identical pieces of paper. The pieces of paper are then put into a hat and mixed together. If a piece of paper is selected at random from the hat, what is the probability that the number on it is a multiple of 3 ?
The correct answer is:
The multiples of ‘3’ from 1 to 20 are 3, 6, 9, 12, 15, 18

During mineral formation, the same chemical compound can beco me different minerals depending on the temperature and pressure at the time of formation. A phase diagram is a graph that shows the conditions that are needed to form each mineral. The graph above is a portion of the phase diagram for aluminosilicates, with the temperature T, in degrees Celsius (°C), on the horizontal axis, and the pressure P, in gigapascals (GPa), on the vertical axis.
P = −0.00146T + 1.11
An equation of the boundary line between the andalusite and sillimanite regions is approximated by the equation above. What is the meaning of the T-intercept of this line?
