In preparation for the coming season, a bass fisherman decides to buy 5 random l

Question

Explanation / Answer

Solution:

Total number of lures = 10

Total number of Crazy Crawler = 1

Probability of Crazy Crawler = 1/10 = 0.10

Probability of not selecting Crazy Crawler = 1 – 0.10 = 0.90

Now, we have to find the probability that the fisherman will not select Crazy Crawler which is given as below:

Required probability = nCx*p^x*q^(n – x)

Where, n = 10, x= 5, p = 0.90, q = 1 – p = 1 – 0.90 = 0.10

Required probability = 10C5*0.90^5*0.10^(10 – 5)

Required probability = 252*0.90^5*0.10^5

Required probability = 252* 0.59049* 0.00001

Required probability = 0.001488
