Answer:
7 / 13
Step-by-step explanation:
The number of cards in a standard deck = 52
Number of red cards in a deck = 26
Number of queens in a deck = 4
Selecting a card at random ;
Probability of picking a red card ;
P(red card) = number of red cards / number of cards in deck
P(red card) = 26 / 52
P(queens card) = number of queens / number of cards in deck
P(queens card) = 4 / 52
Number of red queen cards = (red n queen) = 2
P(red or queens card) = P(red) + P(queens) - P(red n queen)
P(red or queens card) = 26/52 + 4/52 - 2/52
= (26 + 4 - 2) / 52
= 28 /52
= 7 / 13

2: B. $44.10
C: C. $570
Step-by-step explanation:
1.
4250 - (4250 x 0.25)
3187.50
3187.50 + (3187.50 x 0.09)
3474.375 which rounds up to
$3,474.38
2.
52 - (52 x 0.2)
41.6
41.6 + (41.6 x 0.06)
44.096 which rounds up to
44.10
3.
500 + (500 x 0.2)
600
600 - (600 x 0.05)
570
