Suppose that there are 100 MBA students in the first-year class. Of these students, 20 of them have two years of work experience, 30 have three years of work experience, 15 have four years of work experience, and 35 have five or more years of work experience. Suppose that a first-year MBA student is selected at random. (a) What is the probability that this student has at least four years of work experience

(a)0.5

(b)0.625

Step-by-step explanation:

Out of 100 MBA students

Total Sample Space, n(S)=100

(a)Let event A be the event  that an MBA student has at least four years of work experience.

n(A)=15+35=50

Therefore:

The probability that this student has at least four years of work experience is 0.5.

(b)Conditional probability that given that a student has at least three years of work experience,this student has at least four years of work experience.

P(at least 4 years|the student has at least three years of experience)

answer:

1. 0.04

2. 0.15

step-by-step explanation:

i just finished that assignment for properties of probability distributions.

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
