Answer: QRU and QRP
hope this helps :D
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
Answer:
Step-by-step explanation:
set 30
1) 90-52 = x
38 = x
2) 90 -15-25=x
50 = x
set 31
1) t = 3m
m = independent
t = dependent
m t

520 miles.
Ross would be driving double the hours so 260x2=520
