Probability of Mutually Exclusive Events Two events are said to be mutually exclusive if … Scroll down the page for examples and solutions. Two events are independent if the following are true: P(A|B) = P(A); P(B|A) = P(B); P(A AND B) = P(A)P(B); Two events A and B are independent if the knowledge that one occurred does not affect the chance the other occurs. If A happens, it excludes B from happening, and vice-versa. 92 0 obj <>stream gq�5�泰�VaVw�h��r�P��89dڏI�B��Ŵ BMa^��{ ��s�(�EÖ\��-Ro5i!�r�V ��V��h��=*Q,��!��,A{թj�{�vt�-R�h�>�+Wbbt��F#5��f��W� �tY��h̘Q�lEXb̕��x��)>�xF>�pY]� �c�Q9r��eO=V^"~�1&Nn�׏1�_7�{�i��U��l��ixR��{�6O��'hp��/�2�~p6eJ�^|i�=��x �j|DZ� ��;�3�/q8��($�:��0S�~(i��C s�"Z Fe��ǘ��\T#�S�MM��$~J;��9�Y?��~� ��Y~�$�:��c'T�f�[Uع��SN�y��gJ��qL5%nH=�,Z7�s�r�-ki �~��H��&N�Dv��Y�]�[ٺ[�ҜJ&d ~V��w��Q+5*Xr�A��|q�/��E��3nؔ�?

Info. The following diagrams show the formulas for the probability of mutually exclusive events and non-mutually exclusive events.

Students have several difficulties with the distinction between independent and dependent events. Two central concepts in probability theory are those of "independence" and of "mutually exclusive" events and their alternatives. ��?�Q��:z�QB�d��-��I��ٚ��*(��mA�`�'�Up^�R$�S��\�R�, ��1j>��壔�[?��덑��_i�BKxt registered in England (Company No 02017289) with its registered office at 26 Red Lion In this article we … Two events A and B are said to be independent if the outcome of event A doesn’t affect the outcome of event B and vice versa. h�d�Aj�0 ��X�Ȳ'm �P_ ��撋#m��U��.�^�\gfe��v[��?��Hӻ*_"B[SYSۧjݬW��y\��?�HWi�^1��F[mUٱ�?٘�o�G��a,�.�eh) ��*�g�\�h��J�G��EG��M��5�Jj�6 For example, the outcomes of two roles of a fair die are independent events.
