5. What is the probability that a number picked from the set {-4,-3,-2,-1,0,1,2,3,4,5) will be a
tatiyna

Answer:

70%.

Step-by-step explanation:

Rearrange the inequality to isolate x. Start by subtracting 5 from both sides of the inequality:

2\,x + 5 - 5 > 1 - 5,

2\, x > -4.

Divide both sides by 2. (Keep in mind that if the multiplier or divisor is smaller than zero, it will flip the inequality sign.)

x > -2.

There are ten numbers in this set. Only seven of them will satisfy this inequality. Note that the ">" symbol means strictly greater than (while "\ge" means greater than or equal to.) As a result, x = -2 will not count as a solution.

Assume that the number is picked randomly.

\begin{aligned}&\text{Probability of Success} \cr = & \dfrac{\text{Number of Choices that lead to Success}}{\text{Number of all Choices}} \cr =& \dfrac{7}{10} \cr = &0.7 \cr =& 70\% \end{aligned}.
