A) \[\frac{7}{100}\]
B) \[\frac{1}{10}\]
C) \[\frac{4}{50}\]
D) \[\frac{9}{50}\]
Correct Answer: B
Solution :
[b] Total number of possible outcomes= 100 |
Let E be the event 'drawing a prime number less than 30'. |
Outcomes favourable to E are |
\[\{2,3,5,7,11,13,17,19,23,29\}\]i.e., 10 in number. |
\[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,P(E)=\frac{10}{100}=\frac{1}{10}\] |
