Abag contains six real diamonds and five fake diamonds. if six diamonds are picked from the bag at random, what is the probability that at most four of them are real?

0.933 ( approx )

Step-by-step explanation:

Given,

Real diamonds = 6,

Fake diamonds = 5,

Total diamonds = 6 + 5 = 11,

If six diamonds are picked from the bag at random,

So, the total ways =

= 462

Also, the number of ways of at most four real diamonds in these 6 diamonds

Hence, the probability that at most four of them are real =

you answer is a
