Asingle card is drawn from a standard 52-card deck. let b be the event that the card drawn is a black, and let f be the event that the card drawn is a face card. find the indicated probability. p(b′∪f) = ?

0.6154 or 61.54%

Step-by-step explanation:

The joint probability P(B′∪F) is given by the sum of each individual probability minus the intersection between both probabilities (red face cards).

The inverse probability of a card being black is also the probability of a card being red, which is 26 in 52. There are 12 face cards in a 52-card deck, 6 of which are not black, therefore:

answer: i believe its b. if you sound out the sentences that sounds wrong.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
