Answer:

A and B are not disjoint.

Step-by-step explanation:

Given that there are two events A and B with prob

P(A)=0.5,

P(B)=0.7

If A and B are disjoint, there should not be any common element between A and B

P(AB) should be 0

But here we find P(A) + P(B) = 1.2>1

Since total probability is 1, there must be 0.2 atleast in P(AB)

which implies A and B cannot be disjoint.

A and B are not disjoint.

Gnoma [55]

Answer:

Step-by-step explanation:

(12 - 2)/(2 - 7) = 10/-5 = -2

y - 12 = -2(x - 2)

y - 12 = -2x + 2

y = -2x + 14
