A probability experiment consists of rolling a fair 6 -sided die. Find the probability of the event below. rolling a number greater than 4

Answers

A six sided die has a 1 in 6 probability of rolling any number.
Out of the numbers 1, 2, 3, 4, 5, and 6, two numbers , 5 and 6, are greater than four.
This mean that out of six possibilities, two will be greater than four, so there is a 2 in 6 probability of rolling a number higher than 4. This can be simplified to 1 in 3.

The probability of rolling a number greater than four on a six sided die is 1 in 3, or 1/3

Final answer:

The probability of rolling a number greater than 4 on a fair 6-sided die is 1/3, calculated by dividing the number of successful outcomes (2, as only 5 and 6 are greater than 4) by the total number of outcomes (6 as it's a 6-sided die).

Explanation:

To find the probability of rolling a number greater than 4 on a 6-sided die, we first need to identify the total number of possible outcomes. Since it's a standard 6-sided die, this would be 6. Then, we consider the number of outcomes that fulfill the condition, which in this case is rolling a number greater than 4. This leaves us with 2 successful outcomes (5 and 6). Therefore, the probability of this event is calculated as follows:

Probability = Number of successful outcomes / Total number of outcomes = 2 / 6 = 1 / 3

So, the probability of rolling a number greater than 4 on a 6-sided die is 1/3.

When the point (-3,2) is reflected across the y-axis, what are the coordinates of the resulting point?

Answers

A reflection across the Y-axis means that the Coordinate's X-value switches signs and the Y-value stays the same. So in the case of (-3,2)
being reflected across the y-axis that means that -3 flips its sign and becomes a normal 3 and the 2 stays the same. Therefore the new coordinate is (3,2)

If sin α = 12/13 , and cosα = 5/13 , then tanα =?It would be great if you could add a few words of explanation

Answers

$sin\alpha=(12)/(13)\n\ncos\alpha=(5)/(13)\n\ntan\alpha=(sin\alpha)/(cos\alpha)\n\ntan\alpha=(12)/(13):(5)/(13)=(12)/(13)\cdot(13)/(5)=(12)/(5)=2(2)/(5)=2.4$

If you draw a right angles triangle you can fill in the values. So since sinx= opposite/hypotenuse then the hypotenuse of the triangle is 13. And the side opposite the angle a is 12. Since cosx= adjacent/ hypotenuse, the adjacent side is 5.
Tanx=opposite/adjacent and therefore tana= 12/5
