The possibilities of transportation: (The first will be for morning, second will be for afternoon)
B, B

It is clearly seen that there are 9 transportation options. 
(Using cab 1 time we have BC, CB, CT, TC. So four of the transportation methods use cab one time.) 
Therefore, the probability that she will use a cab only once is 4/9.  
 
        
             
        
        
        
Answer:
80
Step-by-step explanation:
We have, 75% × x = 60
or, 
75/ 100 × x = 60
Multiplying both sides by 100 and dividing both sides by 75,
we have x = 60 × 100/75
x = 80
