Question 1142248: Find the indicated probability.
100 employees of a company are asked how they get to work and whether they work full time or part time. The figure below shows the results. If one of the 100 employees is randomly selected, find the probability of getting someone who carpools, someone who cycles to work, or someone who works part time.
1. Public transportation: 9 full time, 6 part time
2. Bicycle: 4 full time, 4 part time
3. Drive alone: 35 full time, 30 part time

First check that the sum of all numbers from the Table is 100.


Next consider the three questioned probabilities, one after another, separately.



(a)  Find the probability of getting someone who carpools.


         P = 6%2B6%29%2F100 = 12%2F100 = 3%2F25 = 12%.    ANSWER




(b)  Find the probability of getting someone who cycles to work.


          P = 4%2B4%29%2F100 = 8%2F100 = 2%2F25 = 8%.    ANSWER




(c)  Find the probability of getting someone who works part-time.


          P = %286%2B4%2B30%2B6%29%2F100 = 46%2F100 = 23%2F50 = 46%.    ANSWER
