Answer:
About 84 % of the area is between z equals minus 2 and z equals 2
Step-by-step explanation:
A standard normal distribution refers to a normal distribution with a mean of 0 and a standard deviation of 1.
To find the percentage of area that is between -2<z<2, we are going to use a graphic calculator. We get that P(-2<z<2) = 0.84
Therefore, About 84 % of the area is between z equals minus 2 and z equals 2

<em><u>Incomplete question. However, additional information provided below</u></em>
<u>Step-by-step explanation</u>:
Here is a clearer rendering of the requirements of the question below:
"A supermarket delivers tickets to all its customers, for those who make purchases under $ 10 an orange ticket, purchases between $ 10 and $ 20 a yellow color, between $ 20 and $ 30 a blue color and for those who make larger purchases at $ 40 dollars a green ticket. To choose the winners, spin the roulette (as shown in the figure). Determine the probability that a person who spent $ 25 on purchases will win."
Thus, <u>you are required to focus your probability calculations on the $ 20 and $ 30 customers category who are given a blue color ticket, since a person who spends $25 is within this category.</u>
