Hello guys,
I have a doubt of probability, follows below:
I have a dice with 20 sides and I need to hit the sequence
1,2,3,4,5,6
this is ok (20x19x18x17x16x15 / 6X5X4X3X2X1) = 38,760
the probability of hitting the sequence of 6 random numbers is 1 in 38,760
but how to calculate the probability of hitting 5 numbers out of 6? And 4 numbers out of 6?
I mean, I will throw the dice 6 times and hit 5 numbers
or throw the dice 6 times and hit 4 numbers, how to calculate the probability of hit?
other probability doubt is
I have 5 holes and 2 squirrels
squirrels may appear in the holes:
1 and 2
1 and 3
1 and 4
1 and 5
2 and 3
2 and 4
2 and 5 and so on
how to make this calculation to get the exact number of probability
Thanks
