Amongst a group of 700 students, 210 have opted for science, 150 have opted for arts, while 340 have opted for commerce. If a student is randomly selected from this group, what is the probability that this student would have opted for science?
A
0.25
B
0.48
C
0.45
D
0.3
Correct Option:
D
Explanation
Out of 700 students, 210 opted for Science. Thus,
P(Science)=210/700=3/10=0.30.
So a randomly selected student has a 30% probability of being a Science student.
