A coin toss is used to simulate an experiment. Which of the following must be true about that experiment?
It must have four possible outcomes, each with a probability of 1/4 .
It must have four possible outcomes, each with a probability of 1/2 .
It must have two possible outcomes, each with a probability of 1/2 .
It must have two possible outcomes, each with a probability of 1/4 .
It must have two possible outcomes, each with a probability of 1/2 .
The correct option is (3).
What is Probability?A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1.
As per the given data:
A coin toss is used to simulate an experiment.
For finding probability of any event, we should know the sample space of the event.
The sample space for a coin toss can be obtained by observing all the possible outcomes when a coin is tossed.
Sample space = {H, T}
Where H is heads and T is tails.
There can be 2 possible outcomes, either the coin toss will result in a head or it will result in a tail.
P(H) = 1/2
Similarly
P(T) = 1/2
Hence, It must have two possible outcomes, each with a probability of 1/2 .

Math: There are 30 pages in a chapter of your textbook. You read 40%, how many pages do you have left to read? Explain how to solve this using 2 different methods
Answer:
18 pages left
Way 1: Find what 40% of 30 is and subtracting it from 30, leaving 60% of 30 left:
40% of 30 is 0.4*30 = 12, 30 - 12 = 18
Way 2: Subtract 40% from 100% and multiply it by 30: 100% - 40% = 1 - 0.4 = .6, 0.6*30 = 18
