6. Correct. The answer is false

Sample points and their associated probabilities are shown in the following table:

U,V	0	1	2	3	Totals
0	0	b	2b	3b	6b
1	2b	3b	4b	5b	14b
2	4b	5b	6b	7b	22b
Totals	6b	9b	12b	15b	42b

(a)Since the grand total, 42b, must equal 1, b= 1/42.

(b)From the table P(U=2, V=1)= 5b + 5/42.

(c)From the table

P(U ≥1, V≤ 2) = ∑ ∑ f(u,v)

^{u≥1 v≤ 2}

P(U ≥1, V≤ 2)= (2b +3b + 4b) + (4b + 5b + 6b)

P(U ≥1, V≤ 2)=4/7
