consider the experiment of selecting a card from
an ordinary deck of 52 playing cards and determine the probability
of the stated event.

A red card or a card showing a 5 is drawn.

There are 26 red cards and 2 extra fives. Would my answer be 28/52?

  • Math Probability -

    yes

  • Math Probability -

    Does this mean that we do not count the two red fives as they would already be counted in the reds.

  • Math Probability -

    I would assume that you determined the two probabilities separately.

    Red cards = 26/52

    5 = 4/52

    Either-or probability determined by adding the individual probabilities.
