Bumek [7]

Answer:

Darius is correct if only the median score is considered.

Step-by-step explanation:

Darius scores are; 96, 54,120, 87, 123

arrange the scores in increasing order;

54,87,96,120,123

mean = (54+87+96+120+123)/5 =480/5 =96

median =96

Barb's scores are 92,94,96,98,110

mean=(92,94,96,98,110)/5 =490/5=98

median score=96

⇒if the median score only is considered; then it is a tie because the score is 96 in both players.

Four possibilities have probabilities 0.4, 0.2, 0.2 and 0.2 and values $40, $30, $20, and $10 respectively. The expected value i

LiRa [457]

Answer:

b. $28

Step-by-step explanation:

We have these following probabilities:

0.4 = 40% probability of $40

0.2 = 20% probability of $30

0.2 = 20% probability of $20

0.2 = 20% probability of $10

The expected value is:

We multiply each value by its probability. So

$E = 0.4*40 + 0.2*30 + 0.2*20 + 0.2*10 = 28$

So the correct answer is:

b. $28
