Answer:
Step-by-step explanation:
a/(b+c) < 2a/(a+b+c)
b/(a+c) < 2b/(a+b+c)
c/(a+b) <2c/ (a+b+c)
so a/(b+c)+b/(a+c)+c/(a+b) <2(a+b+c)/(a+b+c)=2
Answer:
85
Step-by-step explanation:
15 times 6 is 90. This is how much money he spends on 6 DVDs if they're all $15. 90 subtracted by 5 (remember - he gets $5 off his entire purchase, not just each individual DVD) would be 85!
Answer:
<h2>4/11</h2>
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
<em>Probability = expected number of outcome/Total number of outcome</em>
If there are group of 11 people, then the total outcome of events will be 11
If we are to select 4 oldest people from the group, then the expected outcome is 4.
Hence, the probability that the 4 oldest people in the group were selected is 4/11.
