Step-by-step explanation:
(7x - 5x) -3 =x+4
2x - 3 = 2x + 7
R = 5n + 5w
r - 5w = 5n
r/5 - w = n
The number is 4.5 because 2 thirds of 4.5 is 3 and 3 plus 4 is 7.
Answer:
Step-by-step explanation:
a) The probability that the hand contains exactly one ace
No of ways of selecting one ace and four non ace would be
=
i.e. α=778320
b) the probability that the hand is a flush
No of ways of getting a flush is either all 5 hearts or clubs of spades or dice
= 
ie. β=5148
c) the probability that the hand is a straight flush
In each of the suit to get a straight flush we must have either A,2,3,4,5 or 2,3,4,5,6, or .... or 9,10, J, q, K
So total no of ways = 
γ=46332
