A recent survey of post-secondary students in London asked the students which type of smartphone they had. The results are summarised in the table below:

	iPhone	Samsung	Blackberry
Western	475	293	132	900
Fanshawe	375	137	88	600
	850	430	220	1500

• In blank #1, enter the probability that a randomly selected student has an Blackberry, given that they go to Western.
• In blank #2, enter the probability that a randomly selected Fanshawe student has an iPhone.
• In blank #3 enter the probability that a randomly selected student goes to Western if they have a Samsung.
• Are the events "Western" and "Samsung" independent? Enter "yes" or "no" in blank #4.
