As it is given that a18 − a14 = 32
(a + (18-1)d) - (a + (14-1)d) = 32
a + 17d - a - 13d = 32
4d = 32
d = 8
Hence required common difference is 8....

Since 2x, (x+10) and (3x+2) are in AP we obtain,
(x + 10) − 2x = (3x + 2) − (x + 10)
-x + 10 = 2x -8
-x - 2x = -8 -10
-3x = -18
x = 6
Hence answer is x = 6 ...

Total number of cards is 52
So n(S) = 52
Total number of red king is 2
So n(E) = 2
The probability of getting a red king P(E) = n(E)/n(S)
P = 2/52 = 1/26
Hence answer is 1/26...

Total number of eggs is 400
So n(S) = 400
Let a is the total number of bad egg
So n(E) = a
Probability of getting bad egg is 0.035
So P(E) = 0.035
As P(E) = n(E)/n(S)
So 0.035 = a/400
a = 40...

Total number of sold tickets are 6000.
So n(S) = 6000
Let she bought x tickets
So n(E) = x
Probability of winning the first prize in a lottery is 0.08
So P(E) = 0.08
As P(E) = n(E)/n(S)
So 0....
