Complete question is;

A family of 6 is visiting a mall. The mall has 10 exit doors. Assume random selection. Find the probability that

a. No family member chooses the same exit door.

b. Every family member chooses the same exit door.

Answer:

A) 0.6

B) 0.1

Step-by-step explanation:

A) We are told there are 10 exit doors and the family consists of 6 people.

This implies that for them not to choose the same exit door there will be 6 different doors they will pass.

Thus;

Probability that the no family member chooses the same exit door = 6/10 = 0.6

B) If they all choose the same exit door, it means only 1 out of the 10 exit doors will be used by them.

Thus;

Probability that every family member chooses the same exit door = 1/10 = 0.1

One triangle on a graph has a vertical side of 7 and a horizontal side of 12.
Alisiya [41]
If you are working out the diagonal line you need to use Pythagoras Theroum: c² = a²+b²

c² = 7²+12² = 193
√c² = c = √193 = 13.89

The length of the diagonal side is 13.89,

Find the radius of a circle that has an area of 6.76 cm². Use it for pi.
Inessa05 [86]

Answer:

<h2>radius = 1.47 cm</h2>

Step-by-step explanation:

Area of a circle = πr²

where

r is the radius

From the question

Area = 6.76 cm²

To find the radius substitute the value of the area into the above formula and solve for the radius

That's

6.76 = \pi \:  {r}^{2}

Divide both sides by π

We have

{r}^{2}  =  \frac{6.76}{\pi}  \\ r =  \sqrt{ \frac{6.76}{\pi} }

r = 1.46689291

We have the final answer as

radius = 1.47 cm

Hope this helps you
