Answer:
Jelly beans(x)=$6
Gummy worms(y)=$7
Step-by-step explanation:
2x+2y=26
2x+3y=33
Therefore Gummy worms are $7 because 33-26 is 7, then you multiply the 7 by 3.
2x+21=33
2x=33-21
2x=12
x=6
The probability is P = 0.004, so the correct option is D.
<h3 /><h3>How to find the probability?</h3>
We want to find the probability that 4 students lie on these 30% subgroup.
We know that there are 30 students, the 30% of 30 is:
x = (30%/100%)*30 = 9
So 9 out of 30 students prefer the tests to be on Mondays.
The probability that the first randomly selected kid wants the test to be on Monday is:
p= 9/30
For the next kid, the probability is:
p'= 8/29 (because one kid was already selected).
For the next one:
p'' =7/28
For the final one:
p''' =6/27
The joint probability is the product of these 4:
P = (9/30)*(8/29)*(7/28)*(6/27) = 0.004
So the correct option is D.
