(a) Yasir travels to work either by car, bus, train or bike. The probabilities of using these means of transport on any work day are shown in the table. [Table with Means of transport and Probability] (b) Yasir records the length of time he spends at work on each of 70 work days. The table shows the results. [Table with Time (t hours) and Frequency] (i) Complete the histogram to represent the data. [Figure showing histogram grid]

1. (a)(i)Find p.[1]
2. (a)(ii)Find the probability that on Monday and Tuesday he travels to work by train on one day and by bus on the other day.[2]
3. (a)(iii)Find the probability that he travels to work by bus at least once on Wednesday or Thursday.[3]
4. (b)(i)Complete the histogram to represent the data.[3]
5. (b)(ii)Yasir starts work each day at 9.00 a.m. He is paid overtime if he works later than 5.15 p.m. Estimate the number of days he is paid overtime during these 70 work days.[2]
