Cumulative Probability distribution |
0.35 |
(0.35 + 0.30) =0.65 |
(0.35+0.30+0.12) = 0.77 |
(0.35+0.30+0.12+0.15) = 0.92 |
(0.35+0.30+0.12+0.15+0.08) = 1 |
Probability that there will be at least two applicants = P (2) + P (3) + P (4)
= 0.12 + 0.15 + 0.08
= 0.35
Probability that there will be at max three applicants = P (0) + P (1) + P (2) + P (3)
= 0.35 + 0.30 + 0.12 + 0.15
= 0.92
Probability that there will be at three or four applicants = P (3) + P (4)
= 0.15 + 0.08
= 0.23
