Answer 1

Answer:

$\huge\underline\bold {Answer:}$

There are 52 cards, so total number of possible outcomes = 52

(a) There are 26 black cards, so P(black card)

= 26/52

= 1/2

(b) There are 4 sevens, so P(seven)

= 4/52 = 1/13

(c) There are 2 red Queens, so P(red Queen)

= 2/52

= 1/26.

Answer 2

Answer:

Total number of cards = 52

Therefore total number of total of total outcomes = 52

a) There are 26 cards so P(black card) = 26/52

= 1/2

b) There 4 sevens so P(seven)

= 4/52 = 1/13

There are 2 red Queens So, P(red queen) = 2/52

= 1/26.

Thank you.
