Answer:
0.125 is the probability of getting a heads on each of the three coins on the one toss of the three coins.
Step-by-step explanation:
We are given the following in the question:
Event: flipping three coins at the same time
We can write the sample space as:
S:{TTT, THH, HTH, HHT, TTH, HTT, THT, HHH}
We define probability as
We have to evaluate the probability of getting a heads on each of the three coins on the one toss of the three coins
0.125 is the probability of getting a heads on each of the three coins on the one toss of the three coins.
Answer:
P=1/42.
Step-by-step explanation:
We know that the student council has 10 members where 5 of the members are Seniors. They need to choose a President, Vice President, Secretary and Treasurer. We calculate the probability that the President is a Senior:
We calculate the number of possible combinations:
Number of favorable combinations is 5.
Threfore, the probability is
P=5/210
P=1/42.
Answer: 90 degrees clockwise
This is equivalent to 270 degrees counterclockwise
The rule for either rotation is
The x and y coordinates swap places, and the new second coordinate flips from positive to negative (or vice versa).
The diagram below shows an example of this for the point (-4,-2) rotating to (-2, 4). The center of the rotation is the origin (0,0).
