Answer:
Step-by-step explanation:
(7/12) of 840 attended the concert:
(7/12)*(840) = 490 students attended the Spring Concert.
(840 - 490) = 350 did not attend
(350/840) is the fraction of students who did not attend. This can be reduced to (35/84)
(350/840) = 0.4167 or 41.67% did not attend.
The correct answer is Choice B: 0.3098.
To find the answer, you have to use a normal distribution table. Look up the percents for each z-score and subtract them to find the region between.
z = 1.92 the percent is 0.9726
z = 0.42 the percent is 0.6628
0.9726 - 0.6628 = 0.3098

Answer:
The probability that each player will receive three picture cards = 0.0324
Step-by-step explanation:
As given,
A deck of 52 cards contains 12 picture cards
Remaining card = 52 - 12 = 40
So,
Total number of ways in which 12 picture card is distributed = 
Now,
The Total number of ways in which Remaining cards are distributed = 
So,
Total number of ways of getting 3 picture card and remaining card =
×
= 
Now,
Total number of ways to distribute 52 cards so that each people get 13 card = 
∴ The probability = 
=
×
=
×
=
×
=
×
= 0.0324
∴ we get
The probability that each player will receive three picture cards = 0.0324
