In a concert band, the probability that a member is in the brass section is 0.50. The probability that a member plays trombone,
kirill [66]

Answer:

B. 0.12

Step-by-step explanation:

To obtain this probability, you need to multiply the two probabilities.. since it's comprised of two events: one that he's in the brass section, one that he plays trombone.  The probably of him playing trombone only happens if he's in the brass section.

So, you have the possibility he's in the brass section: 0.50

The possibility he's playing trombone, if he's in the brass section: 0.24

P = 0.5 * 0.24 = 0.12

25% of €40:00 = €<br> And explain it
Wewaii [24]

Answer:

The correct answer is €10.00

Step-by-step explanation:

50% of 40 is 20. 50% of 50 is 25, so what you do is just take 20 and multiply that by 0.5 or you can just take 40 and multiply that by 0.25.

I really hope this helps you out!
