Students were asked in recent survey whether they prefer meal plan (yes or no). They were also asked about their academic degree (undergraduate, M.B.A., Ph.D.). The survey encompassed 1030 students. Their responses are documented in this table:

		Academic degree
		Undergrad	M.B.A.	Ph.D.
Prefers meal plan	Yes	150	50	200
No	50	150	430

Suppose one student is selected at random. Using this data, find the probabilities:

1. The student is not pursuing a Ph.D. degree? (3 points)
