Step-by-step explanation:
Using the normal distribution, there is a 0.1587 = 15.87% probability that’s a car picked at random is traveling at more than 100 km/hr.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The probability that’s a car picked at random is traveling at more than 100 km/hr is <u>one subtracted by the p-value of Z when X = 100</u>, hence:
Z = 1
Z = 1 has a p-value of 0.8413.
1 - 0.8413 = 0.1587.
0.1587 = 15.87% probability that’s a car picked at random is traveling at more than 100 km/hr.

Answer:
Step-by-step explanation:
The probability of rolling a 3 on a six-sided die is
The probability of rolling a 2 on a six-sided die is also
To find the probability of both event occurring one after another, we multiply the chance of each of the events happening.
So
Answer:
125 cm^3
Step-by-step explanation:
Find THE volume of this cube of side length 5 cm:
Volume of a cube is V = s^3, where s is the side length.
Here, V = (5 cm)^3 = 125 cm^3
