Answer: 
Step-by-step explanation:
Since, The total number of student = 300
Out of which,
The number of students who are only in Maths = 120
And, The number of students who are only in Science = 50
While, the students who are not from any subject = 100
Hence, the number of student who are from both maths and science = Total student - Maths student (only) - science student (only) - None
= 300 - 120 - 50 - 100
= 30
That is, there are 30 students who are both from science and maths,
Thus, the probability of selecting one student who is both from maths and science = 30/300 = 1/10
Answer:
area of this circle: 490.6 inch²
Step-by-step explanation:
area of circle: π(radius)²
Here the diameter is given 25 inch, so the radius will be half: 25/2 → 12.5 in
using the formula:
3.14(12.5)²
490.625 inch²
490.6 inch²____rounded to nearest tenth.
