let event is X
so
P(X)=75%=0.75
probabilty that event will not happen
P(X')=1-P(X)
P(X')=1-0.75
P(X')=0.25
so
probabilty that event will not happen is 0.25

If the probability that an event will happen is .25 or 25 percent what is the probability that it will not happen?
The total probability of something happening plus the probability of that same thing not happening is 1, or 100 % → probability of not happening = 1 - 0.25 = 0.75 or 100 % - 25 % = 75 %
What is a probability of 75 percent?
probability of 75 percent = 3/4
The probability of an event is 20 percent How many times should you expect this event to occur in the given number of trials 15 trials 40 trials 75 trials 120 trials?
15 trials: 3 times 40 trials: 8 times 75 trials: 15 times 120 trials: 24 times But don't bet on it.
What is the probability of two events happening together when on their own the first event happens 75 and the second event happens 50?
If the two events are independent then the probability of them both happening is Pr(event1) X Pr(event2). Which in your case is 0.75x0.50=0.375 which translates into 37.5%
What is 0.5 percent of 75 liters?
0.5 percent of 75 liters is 0.375l.
If the probability that an event will happen is .25 or 25 percent what is the probability that it will not happen?
The total probability of something happening plus the probability of that same thing not happening is 1, or 100 % → probability of not happening = 1 - 0.25 = 0.75 or 100 % - 25 % = 75 %
What is a probability of 75 percent?
probability of 75 percent = 3/4
What is the probability of failing 75 times on a 2 percent chance of success?
If the probability of succeeding is 2%, then the probability of failing is 98%. The probability, then, of failing 75 times is 98%75, which is 22%.
What would be the best probability 99 out of 100 or 1 or 2 or 75 percent?
99 out of 100 is the best.
What is the probability of getting 75 percent on a four question quiz?
The answer depends on how well you do in the quiz: that is not a random experiment.
What is the defionition of probability?
Probability is the frequency that something in particular will happen, expressed in ratio with the frequency of anything happening. For instance, if you say that the probability of something is 0.25, then you can expect, over the long run, that repeated trials will result in 25% of the desired results and 75% of the non desired results. A concrete example: In a standard deck of 52 cards, there are 12 face cards, the Jack, Queen, and King of Spades, Diamonds, Clubs, and Hearts. The probability of drawing a face card from a randomly shuffled deck is 12 in 52, or 3 in 13, or about 0.2308. Probability is always a number between 0 and 1. A probability of 0 means that the desired event will never happen, and a probability of 1 means that the desired event will always happen. A consequence of this definition is that, if you say that the probability of something happening is p, then the probability of that something not happening is 1 - p.
The probability of an event is 20 percent How many times should you expect this event to occur in the given number of trials 15 trials 40 trials 75 trials 120 trials?
15 trials: 3 times 40 trials: 8 times 75 trials: 15 times 120 trials: 24 times But don't bet on it.
If there is a 75 percent chance of rain on Monday and a 25 percent chance of rain on Tuesday what is the probability of rain on either Monday or Tuesday?
thirteen sixteenths.
What is the percent of 75 percent?
The percent of 75% is 75%.
If something is 75 percent more likely to happen how many more times is it likely to happen?
three times.
What is the probability of two events happening together when on their own the first event happens 75 and the second event happens 50?
If the two events are independent then the probability of them both happening is Pr(event1) X Pr(event2). Which in your case is 0.75x0.50=0.375 which translates into 37.5%
