Answer:
Kyle plays the tuba.
Randy plays the trumpet.
Ben plays the flute.
Step-by-step explanation:
Let's analyze the given information:
The trumpet player isn't Kyle.
Randy sits next to the tuba player.
Ben plays the flute.
Now, let's deduce the information:
Kyle is not the trumpet player.
Randy is not the trumpet player (as Kyle isn't).
Since Randy sits next to the tuba player, Randy is not the tuba player, so he must be the other player sitting next to the tuba player.
This leaves Kyle as the tuba player.
Since Ben plays the flute and Kyle is the tuba player, Randy must be the trumpet player.
In conclusion:
Kyle plays the tuba.
Randy plays the trumpet.
Ben plays the flute.
