I still do not understand fractions??????
2/3 + 1/3 + 5/6 =
divide all of them first then add them up
???. I am still lost, can someone please help me.
Ok. In your earlier question, there was talk of the LCM, the least common multiple. Whenever you add fractions, the denominator has to be the same. As my old math teacher used to say, you can only add apples to apples, not shoes. Anyway, you need to find the denominator that is common to all those numbers. Here, the only denominators are 3 and 6. What is the Least Common Multiple here? It's not 3, because 6 can't go into 3. 6, however, would work, because 3 can go into 6 twice.
Let's use 6. Now, 5/6 can stay untouched. It's already got the LCM. 2/3 and 1/3 need some work. To get the denominator to be 6, we have to multiply it by 2. If we multiply the denominator by 2, we have to do the same to the numerator, otherwise we change the value of the fraction. So, 2/3 times 2/2 gives us 4/6. Do the same with 1/3. 1/3 times 2/2 gives us 2/6.
Now, the problem is 4/6 + 2/6 + 5/6. Are you good from there?
what is a depenent event
A dependent event refers to an event where the outcome of one event affects the outcome of another event. In other words, the probability or occurrence of the second event is influenced by the outcome of the first event.
To explain how to identify a dependent event, let's take an example of drawing cards from a deck. If you draw a card from a standard deck of 52 cards without replacement, the events of drawing two cards would be dependent.
For instance, if you draw an Ace as your first card, there are only 3 Aces left in the deck for your second draw. Therefore, the probability of drawing an Ace on the second draw would be influenced by the outcome of the first draw.
On the other hand, if you were drawing cards with replacement, where the drawn card is placed back into the deck before the second draw, the events would be independent. In this case, the outcome of the first draw does not influence the probability of the second draw since the deck is unchanged.
In summary, a dependent event is when the outcome of one event affects the probability or occurrence of another event, typically when events are related or dependent on each other in some way.
