Jack picked a card from a standard deck, looked at it, and then put it back. he then picked a second card. what is the probability that jack picked a diamond or a queen on either pick?

Solution:

Total umber of Cards in a deck of cards = 52

Total number of Diamonds in pack of 52 cards = 13

Total number of queen = 4

Number of Diamond cards and Queen =13 diamonds(Which includes 1 queen) + 3 queens which are not diamond=16( Favorable outcome)

Probability that Jack picked a diamond or a queen on either pick=Diamond(13)+3 Queen=(16 in number) =

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.
