Acontainer has 3 apple juice boxes, 4 grape juice boxes and 5 orange juice boxes. alex picks one juice box, drinks it and then picks another juice box. what is the probability that alex picks grape juice and then orange juice?

Hey!

Grape over total:

After he drinks 1, there will be 1 less. That means it will be over 11

Orange over total:

Now multiply the fractions

That means the probability is:

Good luck and hope this helps! :)

tickets for the harlem globetrotters

show at michigan state university in

2010 cost $16, $23, or, for vip seats, $40.

total revenue = 16x + 23y + 40z

if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, if 9 times as many $16 tickets were sold

as vip tickets,

x = 9z => x – 9z = 0, sales of all three kinds of tickets would

total $46,575.

16x + 23y + 40z = 46575, how many of each kind of ticket would

have been sold?

solve for x, y and z

x − 9z = 0

x − y − z = 55

16x + 23y + 40z = 46575

x = 1170

y = 985

z = 130
