Question

Buses pass a point at random, 20% of the bus belong to Sockey Joe. If X is the rv representing the number if buses observed until the (including) the first Sockey Joe, show that. G(t) = t/5-4t​

Answer 1

To find the probability, we need to calculate P(change|bus), which represents the probability that a randomly chosen student has change given that he or she rode a bus within the last month.

Step-by-step explanation:

To find the probability, we need to calculate P(change|bus), which represents the probability that a randomly chosen student has change given that he or she rode a bus within the last month.

We can calculate this probability by dividing the number of students who have change and rode a bus by the total number of students who rode a bus.

Let's say there are 100 students who rode a bus, and out of those, 30 students have change. Then the probability is 30/100 = 0.3, which can also be expressed as 30%.
