Question Help A teacher wants to find out whether coin flips of dimes have a flip dimes until the end of cl Select all that apply 50% chance of co ng up tails In the last 5 minutes of class, he has all the students ass and then report their results to him. Which condition(s) for use of the binomial model is/are not met? A. The trials are independent. B. The probability of success, p, is constant C. The number of trials is fixed. D. There are two possible outcomes E. All the conditions for the binomial model are met

Explanation / Answer

Here the conditions for the use of binomial models that are not met are:-

1. The probability of success, p, is constant.

Here each students flips the dimes. Thus each will have different probability of getting tails. Thus the probability of success p is not constant.

2. The number of trials is fixed.

The students will flip the dimes for 5 minutes for innumerable number of times. Here they have time limit. Thus the number of trials is not fixed.

The remaining two conditions hold i.e. the trials are independent and there are two possible outcomes-head and tail.
