If events A and B are independent, and the probability that event A occurs is 83%, what must be true?

1 answer:

3 0

The probability of event B occurring is 17%.
Imagine that you enter 83 raffle tickets and a friend of yours enters 17 tickets. If you two are the only ones who enter, the chance you have (83%) + the chance your friend has (17%) will equal the 100% chance that either one of you or your friend's raffle ticket will be drawn.

I hope this helps!

5x + 10 = 20

Andrei [34K]

To solve for x, we must first isolate the term containing x which in this problem is 5x.

Since 10 is being added to 5x, we subtract 10 from both sides of the equation to isolate the 5x.

On the left, the +10 and -10 cancel out and on the right, 20 - 10 is 10 and we have 5x = 10.

Now we can finish things off by just dividing both sides of the equation by 5. On the left the 5's cancel and on the right, 10 divided by 5 is 2 so x = 2.
