ap ks formula sy kr rahy bro?

The first is 4C3*5C3 all divided by 9C6, the number of ways of choosing the 6 flowers.
=4*10/84=40/84
That is 10/21
The other possibilities are 2 red, 4 white, which is 30/84, 1 red and 5 white, 4 ways, and 4 red 2 white, which is 10 ways.

at least 1 is the same as 1-none.
probability of none is e^(-2)*2^0/0! or e^(-2)=0.1353
1- that probability is 0.8647.
