  Anyone can advise how to do this qn (with workings)

  In a simple experiment of rolling a six-sided dice, the following events were defined:

  E = {Numbers bigger than 4}

  F = {Odd Numbers}

  Find the probability of Event E or Event F occurring. Show your workings utilizing the General Addition Rule.

   

  Thanks

  Hi,

    Follow the approach below:

    1. List the elements of the sets E, F, and E intersect F.

    2. Find P(E occurs), P(F occurs) and P(E and F occur).

    3. Apply the result P(E or F occurs) = P(E occurs) + P(F occurs) - P(E and F occur).

    Thanks.

  Cheers,
  Wen Shih
