Answer:
18, 13, 19
Explanation:
Number of computer programmers proficient only in Java = 45 - ( 1+1+6) = 37
Number of computer programmers proficient only in C++ = 30 - (6+1+5) = 18
Number of computer programmers proficient only in python = 20 - ( 1+1+5) = 13
Number of computer programmers are not proficient in any of these three languages = 100 - ( 37 + 18 + 13 + 1+ 1+ 5+ 6 ) = 100 - 81 = 19

Answer:
Its nCr = n!/(r!.(n-r)! =n!/!!.(n-1)! = n
Explanation:
Here. the arrangement of outcome does not matters, and hence it is a combination. You should know that when arrangement matters then we have to calculate the permutation and its formula is n!/(n-r)!. However, here it is the combination, and hence its nCr or n!/r!. (n-r)!. And here r is 1 as we can have all heads or all tails. And n is n. Hence,
Its nCr = n!/(r!.(n-r)!
=n!/!!.(n-1)!
= n
