A number cube with faces labeled from 1 to 6 will be rolled once.
kramer

Answer:

\Omega=\{1,2,3,4,5,6\}

A=\{1,2,3,4\}

Step-by-step explanation:

<u>Sample Space</u>

The sample space of a random experience is a set of all the possible outcomes of that experience. It's usually denoted by the letter \Omega.

We have a number cube with all faces labeled from 1 to 6. That cube is to be rolled once. The visible number shown in the cube is recorded as the outcome. The possible outcomes are listed as the sample space below:

\Omega=\{1,2,3,4,5,6\}

Now we are required to give the outcomes for the event of rolling a number less than 5. Let's call A to such event. The set of possible outcomes for A has all the numbers from 1 to 4 as follows

A=\{1,2,3,4\}

Referring to triangle ABC, find the area of the triangle.
kondaur [170]

Answer:

Area = 337

Step-by-step explanation:

Given

a = 42.5

c = 35.5

B = 153.5^\circ

Required

Area of triangle

This is calculated as:

Area = 0.5 *a* c * \sin(B)

This gives:

Area = 0.5 *42.5* 35.5 * \sin(153.5)

Area = 0.5 *42.5* 35.5 * 0.4462

Area = 336.602125

Area = 337 --- approximated
