Three hundred high school seniors were surveyed about their intended college majors. The results are displayed in the Venn Diagr

atroni [7]

Answer: $\frac{1}{10}$

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

The train to Boston traveled at an average speed of 50 miles per hour for 5 hours. The train to Hartford traveled at an average

lawyer [7]

To find how many miles per hour you need to divide 50 by 5 to get the number of miles per hour and do the same thing to the 2nd step and to find the difference you need to subtract the numbers. Hope it helps!!!
