Question

Someone please help me with this type of problem, I tried multiple times but still couldn't get the correct answer. I'd appreciate so much! :(

Answer 1

As per given by the question,

There are given that;

7 plain pencils and 5 pens in first box, and 5 color pencils and 5 crayons in the second box.

Now,

The total number of item in the first box is 7+5=12, and

The total number of item in the second box is 5+5=10.

Then,

The probability that, a plain pencil from the first box is,

`(7)/(12)`

The probability of color pencil from the second box is,

`(5)/(10)=(1)/(2)`

So,

The probability that a plain pencil from first box and a color pencil from the second box is,

`\begin{gathered} P=(7)/(12)*(1)/(2) \\ =(7)/(24) \end{gathered}`

Hence, the probability that a plain pencil from first box and a color pencil from the second box is,

`(7)/(24)=0.292`
