(red, green) add up to 7 = (1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1)
(red, green) add up to 11 = (5, 6), (6, 5)
P(add up to either 7 or 11) = 8/36 = 2/9
Answer:

Step-by-step explanation:
Given inequality is 
Simplifying the inequality by rearranging the terms:

=> 
=> 
=> 
So the given inequality can be simply expressed as 
Hence x can take all values in the domain which are less than 2.
Convert 1/4 and 3/10 to have a common denominator:
1/4 = 5/20
3/10 = 620
Now you have 2 5/20 + 4 6/20 = 6 11/20
The answer is A.
Answer:
<u>The</u><u> </u><u>requ</u><u>ired</u><u> </u><u>num</u><u>ber</u><u> is</u><u> </u><u>7</u><u>0</u><u>.</u>
Step-by-step explanation:
let the no. be 10y + x where x is unit digit and y is ten's digit.
given , sum of the digit is 7
x + y = 7 ...(1)
also , reversing the no. we get 10x + y ,where x is ten's digit and y is unit digit.
given reversed digit decreases the number by 63 .
so, 10y + x - ( 10x + y ) = 63
9y -9x = 63
( dividing both side by 9 )
y - x = 7 ....(2)
adding 1 and 2 [ refer attachment ]
so the required original number is
10y + x = 10×7+0 = 70
Answer:
190
Step-by-step explanation:
10x5x2=100
5x3x2=30
3x10x2=60
100+30+60=190
