May anyone give me an example of a independent and an dependent probability word problem about food?

Rufina [12.5K]

Dependent: Ventus has a bag of chex mix and he spent his time counting and organizing the food. There are 13/31 white pieces of chex, 10/31 pretzels, and 8/31 cracker bites. he wants to see if he can grab two white chex pieces, one at a time without replacing the first attempt. He reaches his hand into the bag and gets a white chex piece and doesn't replace it. What is the probability that Ventus will grab another white chex?
independent: Cabel has a bowl of fruit and his sister won't let him take one and look at it for some strange reason/ however, she does tell him the probability of picking each fruit out of 12. 2/6 oranges, 3/12 apples, and 5/12 bananas. He must replace every fruit he picks. What is the probability of picking an orange?

Darren is painting a wooden block as part of his art project The block is a rectangular prism that is 12cm long by 9 cm wide by

Ksenya-84 [330]

Answer:

<h3>The surface area in square meters that Darren has to paint is $426cm^2$ </h3><h3>∴ $A=426cm^2$ </h3>

Step-by-step explanation:

Given that Darren is painting a wooden block is a rectangular prism

Its length is 12 cm ,width is 9 cm and height is 5 cm

<h3>To find the surface area in square meters that Darren has to paint :</h3>

Let l be the length, w be the width and h be the height

Then l=12 cm , w=9 cm and h=5 cm

The formula for the Surface area is

A=2(lw+wh+hl) square units

Substitute the values in formula we get,

A=2(12(9)+9(5)+5(12))

=2(108+45+60)

=2(213)

=426

<h3>∴ $A=426cm^2$ </h3><h3>∴ the surface area in square meters that Darren has to paint is $426cm^2$ </h3>
