If a person is selected randomly from the town, what are the odds against selecting someone who commutes by bicycle? 19) 19 :5 A) 4:1 B) 1:4 termine whether the events are mutually exclusive. 20) 20) Draw one ball colored red from a bag. Draw one ball colored blue from the same bag. B) No A) YesExplanation / Answer
18. Percentile of value 6 = (Number of values less than 6)/ (Total number of values) * 100
Here,
Number of data values less than 6 = 7
Total number of values = 20
Hence,
Percentile of value 6 = 7/20 * 100 = 35
Option D is correct.
20. Two events are said to be mutually exclusive if they can't occur at the same time.
Here in this situation, we can either draw a red ball or draw a blue ball from the same bag but we can't draw both color balls in one go if we are selecting one at a time.
Hence these two events can't occur together. So,
The answer is Yes. They are mutually exclusive.
