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.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
