Probability of an Ace= 4/52
Probability of a King = 4/52
Probability of an Ace or a King = P(Ace) + P(King)
=4/52 +4/52
=8/52
=2/13

Answer:
<h3><u>Mean</u></h3>
<u />



<h3><u>Standard Deviation</u></h3>



<h3><u>Summary</u></h3>
Nilo has a mean score of 10 and a standard deviation of 5.23.
Lisa has a mean score of 10 and a standard deviation of 1.83.
The <u>mean</u> scores are the <u>same</u>.
Nilo's standard deviation is higher than Lisa's. Therefore, Nilo's test scores are more <u>spread out</u> that Lisa's, which means Lisa's test scores are more <u>consistent</u>.
