If an event is very likely to occur, the probability is between ____ and ____ on the probability spectrum
dimaraw [331]

If an event is likely to occur, the probability that the event will occur is between 3/4 and 1.

<h3>What is the probability?</h3>

Probability determines how likely it is that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

If the probability lies between 0 and 1/5, it is likely that the event would not occur. If the probability lies between 1/5 and 1, it is likely that the event would occur.

Ten years ago Victors age WAs half of the age he will be in 10 years how old is he now?
ICE Princess25 [194]

By solving a linear equation, we will see that Victor is 30 years old.

<h3>How old is Victor now?</h3>

Let's say that Victor is x years old.

We know that 10 years ago, (x - 10), his age was half of what it will be in 10 years (x + 10).

Then we can write the linear equation:

(x - 10) = (x + 10)/2

Now we can solve that equation for x:

2*(x - 10) = x + 10

2x - 20 = x + 10

2x - x = 10 + 20

x = 30

So we conclude that Victor is 30 years old.

<span>There are 366 days in a leap year
 In a week there are 7 days, so total no of days= 7*52=364 days.
  Here 52 represents number of weeks.
  Now last two days can be combination of two days say like Monday and Tuesday or Tuesday and Wednesday and so on.
 So in total 7 combinations are possible.
 Out of there can be 3 combinations containing Thursday or Friday.
 Hence, the probability is 3/7.
