Answer:
Events 2,4 and 5 have probabilities greater than 0.5
Step-by-step explanation:
They are 10 balls combined: 2blue, 3 red and 5 white with the probabilities:
#We calculate the probabilities to check which events have a probability greater than 1/5=0.2
#choosing 1 blue marble
#choosing 1 red marble
#choosing 1 red marble, not replacing it,
#choosing 1 white marble, replacing it, and choosing another white marble
#choosing 1 white marble
Hence, from our calculations, events 2,4 and 5 have probabilities greater than 0.5
Answer:
133 Students
Step-by-step explanation:
Let the number of student in a van=v
Let the number of student in a bus=b
The senior class at Snellville rented and filled 12 vans and 14 buses with 796 students.
Therefore: 12v+14b=796
General High rented and filled 14 vans and 12 buses with 738 students.
Therefore: 14v+12b=738
We solve the two resulting equations simultaneously
12v+14b=796
14v+12b=738
<u>Multiply equation 1 by 12 and equation 2 by 14 to eliminate b</u>
144v+168b=9552
196v+168b=10332
Subtract
-52v=-780
Divide both sides by -52
v=15
We substitute v=15 to obtain b in any of the equations
12v+14b=796
12(15)+14b=796
14b=796-180
14b=616
Divide both sides by 14
b=44
Therefore a bus contains 44 Students and a Van contains 15 students.
Number of Students who would fill 2 buses and 3 vans
=2b+3v
=2(44)+3(15)
=133 Students
