a) Z-score for Patrisse test grade is 0.7288
b) z-score for Makayla test grade is -0.7441
c) Patrisse did better.
<h3>What is z- score?</h3>
A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.
Z-score for Patrisse test grade.
X= 81.4, = 72.8, = 11.8
Z= x- /
Z= 81.4 - 72.8/ 11.8
Z= 0.7288
Now, z-score for Makayla test grade.
X= 60.6, = 67, = 8.6
Z= x- /
Z= 60.6 - 67/ 8.6
Z= -0.7441
Hence, Patrisse did better as she had better z- score.

We should each breakdown the probability first for scarves, gloves and hat.
Probability of choosing brown scarf = 1/4
<span>Probability of choosing black gloves = 1/3
</span>There may be no specification of the hat so it is still random, any color of the two hats is possible.
Multiply these probabilities together:
1/4 x 1/3 x 2 = 1/6
The probability of this combination of clothes together is 1/6
