Answer:
The probability is 8 over 15.
Step-by-step explanation:
14 of the musicians play both guitar and drums, 28 play drums, 18 play the guitar.
It means n(G and D)=14, n(D)=28, n(G)=18.
Using the formula of Union:-
n(G or D) = n(G) + n(D) - n(G and D).
n(G or D) = 18 + 28 - 14.
n(G or D) = 32.
It says 60 musicians applied for a job at a music school. So n(U)=60.
the probability that the applicant who gets the job plays drums or guitar is = n(G or D)/n(U) = 32/60 = 8/15.
Hence, the probability is 8 over 15.
1) 2, greater than (>)
4/5 = 8/10
8/10 (4/5) > 2/10
2) 1, less than (<)
3/8 = 30/80 | 6/10 = 48/80
30/80 (3/8) < 48/80 (6/10)
Hope this helps! :)

Step-by-step explanation:
We need to apply the following identity:
Then, applying this, you know that for :
We need to remember that:
and
Therefore, we need to substitute these values into .
Then, you get:
