If a card is chosen at random from a pack of 52 playing cards, what is the probability of a Queen or a Club?

1 answer:

6 0

The answer is b because you have 4 queens in a deck of cards and 13 clubs in a deck so if you add them you would get 17/52 cards

Mean: $np=100\times0.20=20$

Standard deviation: $\sqrt{np(1-p)}=\sqrt{100\times0.20\times0.80}=4$
