Question
You conduct a random experiment in which you toss a coin 10 times. How many possible outcomes with exactly 6 heads are there in this random experiment?6105210
Solution
The number of possible outcomes with exactly 6 heads in 10 coin tosses can be calculated using the binomial coefficient, which is a term from combinatorics used in probability theory and statistics.
The binomial coefficient is calculated as follows:
C(n, k) = n! / [k!(n-k)!]
where:
- n is the total number of trials (in this case, 10 coin tosses),
- k is the total number of "successes" (in this case, 6 heads),
- "!" denotes factorial, which is the product of all positive integers up to that number.
So, to calculate the number of possible outcomes with exactly 6 heads in 10 coin tosses, we substitute n = 10 and k = 6 into the formula:
C(10, 6) = 10! / [6!(10-6)!] = 10! / [6!4!] = (10987654321) / [(654321)(4321)] = (10987) / (4321) = 210
So, there are 210 possible outcomes with exactly 6 heads in 10 coin tosses.
