The sum of probability for an event happening and not happening must be equal to 1 because there is a 100% chance that one or the other will occur.
So the probability on not drawing a quarter:
P(!Q)=1-4/5
P(!Q)=5/5-4/5
P(!Q)=1/5
As a percentage:
p/100=1/5
p=100/5
p=20%

Answer:
Step-by-step explanation
You must find the common denominator for all of them.
A is correct. 13 x 2 is 26 and 14 x 2 is 28. Therefore, 13/14 is greater than 25/28.
B is not correct. 4 x 5 is 20 and 9 x 5 is 45. 4/9 is actually less than 21/45.
C is not correct. 5 x 2 is 10 and 6 x 2 is 12. 5/6 is actually less than 11/12.
D is not correct. 4 x 5 is 20 and 5 x 5 is 25. 4/5 is actually less than 8/25.
Answer:
Step-by-step explanation:
Convert 6 hours to minutes so that 6 hours and 16. 3 minutes can be in the same units.
Since 1 hour = 60 minutes, then 6 hours = 6 x 60 minutes = 360 minutes
Since the insect has more minutes to crawl (360 minutes), then we expect more inches to be covered. Therefore, the ratio is 360 minutes to 16.3 minutes
= 360 minutes : 16.3 minutes
= 360 : 16.3
Now express the ratio as fraction and relate it with 30 inches
= 360/16.3 x 30/1
= 10800/16.3
= 662 .576687 and this is approximately 650 inches
Answer = 650 = (C)
