A) \[\frac{9}{25}\]
B) \[\frac{2}{5}\]
C) \[\frac{6}{25}\]
D) \[\frac{23}{50}\]
Correct Answer: B
Solution :
[b] Total number of possible outcomes = 50 |
Let E be the event 'selecting a multiple of 4 aor 5'. |
So, the favourable outcomes are |
\[\{4,8,12,16,20,24,28,32,36,40,44,48,5,10,15,25,30,\] \[35,45,50\}\]i.e., 20 in number. |
\[\therefore \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,P(E)=\frac{20}{50}=\frac{2}{5}\] |
