Probability of compound events: picking a number from 1 to 5 and choosing the color red,white,orblue

Mathematics
1 answer:
Gwar [14]3 years ago
4 0

Answer:

1 in 15, or 6,67%

Step-by-step explanation:

We'll suppose a few things here, because your question isn't very explicit on details.

First, we'll suppose the numbers and the colors are placed in two different bags/bowls.. so you do one pick for a number and one pick for a color, since you talk about compound events.

Second, the question says "picking a number" and "choosing the color...".  We'll assume it means chances of picking a specific number and a specific color... like "Number 3 and color white".

Since they are compound events, you multiply the probability of each one occurring.

First, how many chances to pick a given number from the 5 numbers?

1/5 right?

How many chances to pick a given color from the 3 colors?

1/3 right?

Every time you pick the number 4, you still have 3 possibilities regarding the color.

So, the compound probability is:

\frac{1}{5} * \frac{1}{3} = \frac{1}{15}

1/15 to pick a specific number/color combination.

4. Find the distance between the two points. Round to the nearest tenth if necessary.
Archy [21]

Answer:

Distance = 7.8 units

Step-by-step explanation:

In coordinate geometry, the distance between the 2 points is given by

Distance = \sqrt{(x1-x2)^{2} + (y1-y2)^{2} }

where (x1,y1) and (x2,y2) are coordinates of the 2 points.

Above the 2 points given are, (-2,-1) and (3,5).

<em>x1 = -2 , y1 = -1 , x2 = 3, y2 = 5</em>

<em>Distance = \sqrt{((-2)-(3))^{2} + ((-1)-(5))^{2} }</em>

<em>Distance = \sqrt{61}</em>

<em>Distance = 7.8102 units</em>

To the nearest tenth, Distance = 7.8 units

Need hep teaching my daughter. Janet went to Resturant and left 20% tip. If tip was $3.20 how much was meal? Solve with equation
Stels [109]

Answer:

The meal was $16.00.

Step-by-step explanation:

since the equation for finding the tip is: decimal of percent times total bill, what you want to do is isolate the bill. you do this by dividing both sides by percent and your equation is total cost = tip/percent

let's say our total equation is x.

x=3.20/0.2

x=16

Now check your work.
