You can put this solution on YOUR website! Given that P(A)= 0.4,P(B)=0.5 and P(aUb) is 0.6, the value of p(anb) is? please explain
Draw the Venn Diagram of 2 intersecting and you will see that
(A U B) = (A) + (B) - (A and B)
---
So P(A and B) = 0.4 + 0.5 - 0.6 = 0.3
---------------------------------------------
Aspinner is dividedinto 21 equal sector ,numbered1 through 21. Determine the probability of spinning a number other than an even number
----
Odds 1,3,5,7,9,11,13,15,17,19,21
=====
P(odd) = 11/21
----------------
