In a concert band, the probability that a member is in the brass section is
0 50. the probability that a member plays trombone given that he or she is in
the brass section, is 024

what is the probability that a randomly selected band member is in the brass
section and plays trombone?
a

12%

Step-by-step explanation:

To solve this problem, we need to find the probability that someone is in the brass section and play trombone.

To do this, we can multiply the probability of someone being in the brass section and the probability of someone playing trombone.

Therefore, it is 12% that a randomly selected band members is in the brass section and plays trombone.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet
