The probability of event is =0.5 , and the probability of event is =0.7 . are and disjoint? no yes it is impossible to determine from the information given.

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.

congruent segments

step-by-step explanation:

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
