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 = blank p = blank k = blank

Explanation:

Step1: Identify the number of trials

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

Step2: Identify the probability of success

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

Step3: Identify the number of successes

We want to find the probability of getting exactly 5 heads. So the number of successes $k = 5$.

Answer:

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