Answer: 0.0476
Step-by-step explanation:
Given : Two friends and 5 other people compete with each other for first and second chair in an orchestra.
Total people in this competition= 2+5=7
By permutation , Number of ways to arrange 7 people= 7!
Also, number of ways for two friends end up as first and second chair together= 2 × 5! [ 2 ways to arrange friends on first and second chair and 5! ways to arrange others]
I.e. Required probability = 
Hence, the probability that the two friends end up as first and second chair together = 0.0476
Answer:
14. -53/89
15. 2 29/30
Step-by-step explanation:
Sum of
18/5+(-71/5)
=18/5-71/5
= 18-71/5
= -53/5
Difference between 18/5 and -71/5
=18/5-(-71/5)
=18/5+71/5
=18+71 /5
=89/5
Sum divided by difference
-53/5÷89/5
= -53/5×5/89
= -53/89
15.
1/2+1/3+1/5+x=4
15+10+6/30+x=4
31/30+x=4
31/30-4=x
31-120/30=x
89/30=x
2 29/30=x
