Answer:
Therefore the probability that a pen from the first box and a crayon from the second box are selected is ![\frac5{16}](https://tex.z-dn.net/?f=%5Cfrac5%7B16%7D)
Step-by-step explanation:
Probability:
The ratio of the number of favorable outcomes to the number all possible outcomes of the event.
![Probability=\frac{\textrm{The number favorable outcomes}}{\textrm{The number all possible}}](https://tex.z-dn.net/?f=Probability%3D%5Cfrac%7B%5Ctextrm%7BThe%20number%20favorable%20outcomes%7D%7D%7B%5Ctextrm%7BThe%20number%20all%20possible%7D%7D)
Given that,
Three plain pencils and 5 pens are contained by the first box.
Total number of pens and pencils is =(3+5)=8
The probability that a pen is selected from the first box is
=P(A)
![=\frac{\textrm{The number pens}}{\textrm{Total number of pens and pencils}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctextrm%7BThe%20number%20pens%7D%7D%7B%5Ctextrm%7BTotal%20number%20of%20pens%20and%20pencils%7D%7D)
![=\frac{5}{8}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B5%7D%7B8%7D)
A second box contains three colored pencils and three crayons.
Total number of pencils and crayons is =(3+3)=6
The probability that a crayon is selected from the second box is
=P(B)
![=\frac{\textrm{The number of crayon}}{\textrm{Total number of crayons and pencils}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Ctextrm%7BThe%20number%20of%20crayon%7D%7D%7B%5Ctextrm%7BTotal%20number%20of%20crayons%20and%20pencils%7D%7D)
![=\frac{3}{6}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3%7D%7B6%7D)
Since both events are mutually independent.
The required probability is multiple of the events
Therefore the required probability is
![=\frac58\times \frac36](https://tex.z-dn.net/?f=%3D%5Cfrac58%5Ctimes%20%5Cfrac36)
![=\frac5{16}](https://tex.z-dn.net/?f=%3D%5Cfrac5%7B16%7D)
The answer is b and i know that cause just david’s
To find the decimal value, we must convert 1/2 and 3/4 into decimal.
1/2=0.5
3/4=0.75
Now we just have choose a random decimal in between the decimal.
Let's choose 0.6
Now we have to convert the decimal into a fraction. So we'll multiply the decimal by100.
0.6×100=60
Then we make the 60 into a fractions. 60/100
Then we'll simply the fraction. 60/100÷10=6/10÷2=3/5
There you go. You have your answer.
