What are the options

A box contains 1 plain pencil and 4 pens. A second box contains 5 color pencils and 5 crayons. One item from each box is chosen

Furkat [3]

1 pencil and 4 pens = 5 total

Picking the pencil would be 1/5 ( 1 pencil out of 5 total items)

5 color pencils + 5 crayons = 10 total items.

Picking a color pencil would be 5/10 which reduces to 1/2

To find the probability of both happening, multiply them together:

1/5 x 1/2 = 1/10

The probability is 1/10

Simplify and determine the coefficient of (-2/3x)(3y)(-2x).

aleksandrvk [35]

Answer:

$4x^{2}y$

Step-by-step explanation:

$(-2/3)(3)(-2)=4$

so the coefficient is 4

$(x)(x) =xx^{2}$

When we multiply 2 same variable we add their power

$(x^{2})(y)=x^{2}y$

So the last answer is $4x^{2} y$
