Question

P(A) = 0.3, P(B) = 0.4
Find the max and min probability of A and B

Answer 1

as is the question makes little sense; there is some context missing i think

Answer 2

nothing is missing

Answer 3

we need to find P(A and B)

Answer 4

but what is max and min refer to?

Answer 5

P (A + B) = P(A) + P(B) - P(A*B)

Answer 6

max and min value of P(A and B)

Answer 7

we wont need the formula in this ques

Answer 8

you see, max and min are defined in the context of the material from which this comes from.

Answer 9

min will be 0 since A and B can be disjoint, max will be 0.3 in which case A will be a subset of B, now u see what I was trying to say?

Answer 10

i see clearer now yes :) thank you
