Sean bought 68 3/4 inches of rope . How many 15-inches ropes can he make from it

choli [55]

Length of rope bought by Sean = 68 3/4 inches
   = 275/4 inches
Then
The number of 15 inch rope that can be made by Sean = (275/4)/15
   = 275/(4 * 15)
   = 275/60
   = 4.58
So we can see from the above deduction that Sean can make 4 complete 15 inches ropes and there will be 0.58 inches of rope excess. <span>I hope the procedure and the method of solving is absolutely clear to you. This is the easiest way to get to the solution for such problems.</span>

2) the conditional probability of a request for additional information given that the bid will ultimately be successful = 0.74

3) the posterior probability that the bid will be successful given a request for additional information = 0.65

Step-by-step explanation:

The concept of probability of success and failure was used as well the approach of bayes formular or posterior probability. Keeping in mind that P(Success) + P(Failure) = 1

The detailed steps is as shown in the attachment.
