there are 4 coins. you get a dollar for every head. all four coins are flipped. what is the outcome? what about if you can choos
weqwewe [10]

The outcome for the flip is 2.

Probability:

Probability refer the possibility of the event required.

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favorable outcomes and the total number of outcomes.

Given,

There are 4 coins.

You get a dollar for every head. all four coins are flipped.

To find the outcome of the flips.

The possible outcomes from the initial flip are:

"4 heads" x 1

"3 heads" x 4

"2 heads" x 6

"1 heads" x 4

"0 heads" x 1

This gives an expected return of

=> (4 + 12 + 12 + 4 + 0)/16 = 2

So, the outcome is 2.

Either if you keep it then you have 2 as outcome of the flips, otherwise if you reflip the coins then you will get the same probability for it also.

Victoria correctly determined the area of this parallelogram by adding the areas of the rectangle and triangles.
adoni [48]

Answer:

56 m²

16 m²

88 m²

Step-by-step explanation:

The formula for the area of a rectangle is:

A=L×W (area=length × width)

A=7×8

A=56m²

The formula for the area of triangle is:

1/2×b×h (1/2 × base × height)

A=1/2×4×8

A=2×8

A=16m²

For the total area you will now add the area of each shape. We will multiply triangle area by 2 because there is 2 triangles.

A=56+2(16)

A=56+32

A=88m²
