A die is rolled. What is the probability that the number is a factor of 6 or more than 2? Does this scenario represent mutually
goblinko [34]

Factors of 6 are : 1,2,3 and 6.

Let us find probability of getting the number that is a factor of 6.

P(\text{ The number is a factor of 6})=\frac{4}{6} =\frac{2}{3}

Now let us find probability of getting a number more than 2 (3,4,5,6).

P(\text{ The number is a greater than 2})=\frac{4}{6} =\frac{2}{3}

We can see that these two events are mutually inclusive events. We can find probability of mutually inclusive events by formula P(\text{X or Y})=P(X)+P(Y)-P(\text{X and Y}).  

P(\text{ The number is a factor of 6 and greater than 2})=\frac{2}{6} =\frac{1}{3}

Now we will find probability of getting the number is a factor of 6 or more than 2 using above formula.

P(\text{ The number is a factor of 6 or greater than 2})=\frac{2}{3} +\frac{2}{3}-\frac{1}{3}    

P(\text{ The number is a factor of 6 or greater than 2})= \frac{4}{3}-\frac{1}{3}=\frac{3}{3}=1  

Therefore, our probability will be 1 and this scenario represents mutually inclusive events.

A boat can travel 496 km on 124 liters of fuel. How much fuel will it need to go 84 km?
Anika [276]

Answer:

A boat would need 21 liters to cover the distance of 84 km.

Step-by-step explanation:

Given

A boat can travel 496 km on 124 liters of fuel.

To determine

How much fuel will it need to go 84 km?

It is stated that:

Distance covered in 124 liters of fuel = 496 km

Thus,

Unit rate = 496 km / 124 liters

               = 4 km per liter

Thus,

The distance covered in 1 liter = 4km

In order to determine the distance covered in 84 km, all we need is to divide 84 km by 4.

i.e.

The fuel needed to go 84 km = 84 / 4 = 21 liters

Therefore, a boat would need 21 liters to cover the distance of 84 km.
