Question

Please help Find the indicated probability. The distribution B.A. degrees conferred by a local college is listed below, by major.________ Major Frequency English 2073 Mathematics 2164 Chemistry 318 Physics 856 Liberal Arts 1358 Business 1676 Engineering 868 9313 What is the probability that a randomly selected degree is in Engineering? Find the indicated probability by using the special addition rule. A relative frequency distribution is given below for the size of families in one U.S. city._____ Size Relative frequency 2 0.439 3 0.230 4 0.209 5 0.070 6 0.036 7+ 0.016 A family is selected at random. Find the probability that the size of the family is less than 5. Round approximations to three decimal places.

Explanation / Answer

1) P(Engineering) = n(engineering)/n(total) = 868/9313 = 0.0932

2) P(Size less than 5) = P(2)+P(3)+P(4) = 0.439+0.230+0.209= 0.878
