Question

A student randomly draws a card from a standard deck and checks to see if it is his favorite suit he then returned to card to the deck shuffles and repeats experiment he performs experiment 30 times can the probability of drawing his favorite suit be found by using the binomial probability formula why or why not

Answer 1

Answer:

The binomial probability formula can not be used for this experiment because it does not state the number of times he expects to draw his favorite suit.  

Step-by-step explanation:

The binomial probability formula is expressed as follows:

P (k success in n trials) = $\left \{ {{n \atop k} \right.$ $p^{k}$$q^{n-k}$

n = number of trials, k = number of successes, n-k = number of failures, p = probability of success in one trial and q = 1 - p = probability of failure in one trial.  

In the given problem, all of the variables are known except for 'k', the amount of times that the student predicts he will draw his favorite suit.
