**The negative binomial distribution of order k and some of its properties.**
*(English)*
Zbl 0566.60014

The negative binomial distribution of order k is introduced and briefly studied. First it is shown that it is a proper probability distribution. Then its probability generating function, mean and variance are derived. Finally it is shown that the number of trials until the r th k th consecutive success (r\(\geq 1, k\geq 1)\) in independent trials with constant success probability p \((0<p<1)\) is distributed as negative binomial distribution of order k. The present paper generalizes results of H. D. Shane, Fibonacci Q. 11, 517-522 (1973; Zbl 0298.60010), the author and A. A. Muwafi, ibid. 20, 28-32 (1982; Zbl 0476.60008), and the author, C. Georghiou and G. N. Philippou, Probability theory, Proc. 7th Conf., Brasov/Romania (1982).
