The probability for the z-score is greater than or equal to 1.4 is 0.08076 or 8.076 %.

<h3>What is a z-score?</h3>

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The probability for the z-score is greater than or equal to 1.4 is given as

P(z ≥ 1.4) = 1 - P( z < 1.4}

P(z ≥ 1.4) = 1 - 0.91924

P(z ≥ 1.4) = 0.08076

P(z ≥ 1.4) = 8.076 %

A car license plate is made up of 7 letters or numbers, where the numbers are whole numbers 0 through 9.

Simora [160]

Answer:

0.28

Step-by-step explanation:

To know the probability we first need to know the total number of choices for each character in the license plate. Since there are a total of 10 possible numbers (0-9) and 26 letters in the English Alphabet. Then this means that each character has a total of 36 possible choices. Out of these 36 only 10 are numbers, therefore the probability of the first character being a number is

$\frac{10}{36}$ or 0.2777
