Answer:
6
Step-by-step explanation:
Number of water bottles bought by Sylvia = 24
Number of water bottles sold by Sylvia =
Number of water bottles left with Sylvia =
Number of water bottles bought by Sam = 36
Number of water bottles sold by Sam = Three times as many as bottles as Sylvia sold =
Number of water bottles left with Sam =
It is given that the number of water bottles left with Sylvia and Sam are equal.
i.e.
So, number of water bottles sold by Sylvia = <em>6</em>
Using the binomial distribution, it is found that the probability that he will hit fewer than 8 of the bottles is of 0.012, given by option A.
<h3>What is the binomial distribution formula?</h3>The formula is:
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem, we have that:
- The probability of a bottle being hit is of p = 0.95.
- There are n = 10 bottles.
The probability that he hits fewer than 8 of the bottles is given by:
In which:
Then:
Hence:
The probability that he will hit fewer than 8 of the bottles is of 0.012, given by option A.
