can you explain hw?

Like? Yes (1) | No (1)

P.Pandeeswari 10 years ago

the last digit must be 5,because the number is divisible by 5.so no of choice=1
the 2nd digit can be selected from remaining 5 numbers.so no of choice=4
the 1st digit can be selected from remaining 4 numbers,because here repitation is not allowed. so no of choice=4

therefore,
total no of choice=4*5*1=20

number of possiblities are (x,x,6), (x,6,x), (x,6,6), (6,x,x), (6,x,6), (6,6,x), (6,6,6) => 7combinations
total number of possibilites are 6*6*6 => 216 combinations

Like? Yes | No

shruthi sultanpure 10 years ago

probability of getting 6 on at least one of the three dice= 1-(probability of getting 6 on none of the three)
Since throwing of three dice is independent event.
hence, 1-( (5/6) * (5/6) * (5/6) ) = 1- (125/216) = 91/216

Like? Yes (1) | No

varisha farheen 10 years ago

prob of getting at least one 6 means that one, two or three sixes so 1/6*5/6*5/6+ 1/6*1/6*5/6 + 1/6*1/6*1/6=31/216
