Assume in a class there are 170 understudies. Of those 170 understudies, 90 are guys and 80 are females. Among 90 male understudies, 55 like playing the sport of football and 35 don't care for it. Among 80 female understudies, 10 like playing the sport of football and 70 don't care for it.

1.Represent this data as a cross arrangement or likelihood possibility table.

2.Show likelihood tree graphs for every one of the conceivable arbitrary occasions that can happen (with their probabilities) if an understudy is picked arbitrarily in this class.

HBL Bank Pvt LtD. is considering its ATM use in the Gulshan-e-Iqbal space of Karachi. An example of 30 ATMs showed they were utilized in the given number of times (in a moment or two) on a specific day, as demonstrated in Table 1.
