Exercise 2.10. Math and physics. In a class of 100 people, 60 of them are math majors, and 75 of them are physics majors. There are no students majoring in anything else in this class. This means that some of the students are double-majoring in both math and physics. A student is picked at random. What is the probability the student is double-majoring

Number of both = number of math + number of physics - total students:

Number of both = 60 + 75 - 100 = 35

Probability of picking on with both = 35/100 = 7/20 = 0.35 = 35%

Since the question doesn’t state what format the answer needs to be I have included the fraction, the decimal and the percentage

300pi

step-by-step explanation:

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
