RS points east; R'S' points north, so there has been a rotation 90° CCW.
After that rotation, point S would be at (1, -1). It is actually at (1, 1), so has been shifted 2 units upward.
A sequence that does the desired mapping is
- c. rotation of 90° CCW about the origin
- b. translation 2 units up
Answer:
The probability they each indicate the same tire is
Step-by-step explanation:
There will be 4 cases involved as there are 4 tires.
Probability of choosing front left tire is as there are a total of 4 tires and we need to choose 1.
Now, if all the four students chose the front left tire then the probability is the product of individual probabilities.
Therefore, probability that all 4 students chooses front left tire is:
Similarly, the probabilities of choosing the remaining 3 tires by all the students would be:
,
,
Therefore, the probability that they indicate the same tire is the sum of all these probabilities.
