Answer:
3/8
Step-by-step explanation:
choices: 6,7,8,9 total: 4
odd numbers: 7,9 total :2
P(odd number) = number of odds/ total
=2/4 = 1/2
Then we spin again
number greater than 6: 7,8,9 total :3
P(odd number) = number greater than 6/ total
=3/4
P(odd, > 6) = P(odd, >6) = 1/2 *3/4 = 3/8

The tank can be filled in 15 min, this means that in one min, 1/15 of the tank can be filled.
The tank can be emptied in 10 min, this means that in one min, 1/10 of the tank can be emptied.
the outflow rate - the inflow rate = rate of emptying the tank
1/10 - 1/15 = 1/x
where x is the time it will take to empty the tank
solving, we'll have
1/30 = 1/x
the reciprocal of the equation gives
x = <em>30 min</em>
25 bowls
3/5x=15
1/5x=5
5*5=25
