Answer:
315 degrees
Step-by-step explanation:
Assume that the dial is a perfect circle and therefore makes a full 360 degree rotation. If the dial is already turned 45 degrees, the rotation angle required to return all the way to the initial position is:
You will need to rotate 315 degrees.
Answer:
The value is
Step-by-step explanation:
From question we are told that
The number of types of marbles present jar is n = 3
Generally the probability of drawing a green marble is
Generally the probability of drawing a marble that is not green is
From the question we are told that there will be continuous drawing of marbles from the jar (in such a way that after each marble is drawn it is being replaced) until a green marble drawn
Let m be the number of times marbles has been drawn when a green marble was gotten
it then means that for m - 1 times the marbles where drawn a green marble was not obtain.
Generally the probability drawing m times is mathematically is mathematically represented as
=>
