Question

determine the values of the variables in the binomial probability formula for the following statement: what is the probability of getting exactly 5 “heads” in 10 coin flips? n = p = k = done

Explanation:

Step1: Identify the number of trials

The number of coin - flips is the number of trials. Here, 10 coin flips are made, so $n$ represents the number of trials and $n = 10$.

Step2: Identify the probability of success on a single trial

For a fair coin, the probability of getting a head on a single flip is $p=\frac{1}{2}=0.5$.

Step3: Identify the number of successful trials

We want to get exactly 5 heads. The variable $k$ represents the number of successful trials, so $k = 5$.

Answer:

$n = 10$
$p = 0.5$
$k = 5$
