Question

an estimator for a construction company has a 0.63 probability of winning any particular bid. if she submits 9 bids, what is the probability of winning exactly 6 times? (round your answer to 3 decimal places if necessary.)

Answer 1

0.266

Step-by-step explanation:

, we have that x=6, n=9, and p=0.63. Thus, the probability can be found by,

P(X=6)=9C6⋅0.636⋅0.373=9!6!3!⋅0.636⋅0.373≈84⋅0.0625⋅0.0507≈0.266
