Question

83% of local residents favor building a children's wadding pool. a) If 25 residents are chosen, find the probability that exactly 6 of them favor the building of the pool. b) If 25 residents are chosen, find the probability that less than 6 of them favor building the pool. c) If 25 residents are chosen, find the probability that at least 6 of them favor the building of the pool.

Answer 1

We are given here that: 83% of local residents favor building a children's wadding pool. The distribution for the number of local residents who favor out of 25 is modelled here as:

a) The probability here is computed here as:

Therefore 0 is the approximated probability here.

b) The required probability here is computed as:

Therefore 0 is the approximated probability here.

c) The probability here is computed as:

Therefore 1 is the approximate probability here.
