**5.80 Show that these facts are true.**Use the definition of binomial coefficients to show that each of the following facts is true. Then restate each fact in words in terms of the number of ways that \(k\) successes can be distributed among \(n\) observations.(a) \(\binom{n}{n} = 1\) for any whole number \(n \geq 1\). (b) \( \binom{n}{n-1} = n \) for any whole number \( n \geq 1 \).(c) \( \binom{n}{k} = \binom{n}{n-k} \) for any \( n \) and \( k \) with \( k \leq n \).

We expand left hand side i.e. nCn nCn= n!/n!*(n-n)! We know that 0!= 1 so nCn = n!/n! = 1 This…

Suppose that 3 out of every 5 drivers come to a complete stop at an intersection having flashing red lights in all directions when no other cars are visible. 15 drivers coming to an intersection under these conditions will be randomly selected. Let Y be the count of these selected drivers that come to a complete stop. Y has a binomial distribution where n = ___ and p = ___ . The possible values of Y are whole numbers from ___ to ___ .

The probability that an archer hits the target is p = 0.9, so the probability that he misses the target is q = 0.1. It is known that in this situation the probability that the archer hits the target exactly r times in n attempts is given by the term containing in the binomial expansion of . Find the probability that the archer hits the target exactly three times in five attempts.
Let X be the number of goal chances that result in goals for a football team during n goal chances. Duringout of many matches, the team scores on 20% of the chances. Let x be binomially distributed.Before a new season, the team acquires two new strikers in the hope of increasing the probability of scoringthe goal chances. During the first 116 scoring chances, they scored 29 goals.b) Determine with a hypothesis test whether the probability of scoring on the goal chances has increased. use 5%level. Also calculate the test's p-value.What would the conclusion of the test be if we had used the 10% level?
