Please give the answer for 2nd qns

Please give the answer for 2nd qns b the probability of getting at least One white ban? c What tne probability of getting at least one black ball? d What is the probability of getting both balls Of dfferent colours. 2. A game for two players. Both raises some fingers of one hand. Add the number of fingers. Which sum has the maximum probability? What is that probability?

Dear Student,

The Sample space of all the possible outcomes when both players raises some fingers of one hand is given below: 

If both the players raises 1 fingers of their one hand, then possible outcome: (1,1) and sum = 2
Similarly, 
For TOTAL 3: (1,2)(2,1)
For TOTAL 4: (1,3)(2,2)(3,1)
For TOTAL 5: (1,4)(2,3)(3,2)(4,1)
For TOTAL 6: (1,5)(2,4)(3,3) (4,2) (5,1)
For TOTAL 7: (2,5)(3,4) (4,3) (5,2)
For TOTAL 8: (3,5) (4,4) (5,3)
For TOTAL 9 : (4,5) (5,4)
For TOTAL 10: (5,5)
So n(S) = 25

Here, maximum probability is of getting the sum of two fingers as 6.
And n(6) = 5
Hence probability of getting the sum as 6 = 525 = 15

Hello Salma dear, the all possibilities are listed below
For TOTAL 2: (1,1)
For TOTAL 3: (1,2)(2,1)
For TOTAL 4: (1,3)(2,2)(3,1)
For TOTAL 5: (1,4)(2,3)(3,2)(4,1)
For TOTAL 6: (1,5)(2,4)(3,3) (4,2) (5,1)
For TOTAL 7: (2,5)(3,4) (4,3) (5,2)
For TOTAL 8: (3,5) (4,4) (5,3)
For TOTAL 9 : (4,5) (5,4)
For TOTAL 10: (5,5)
So n(S) = 25
And n(6) = 5
Hence max prob = 5/25 = 1/5
