Final answer:
The probability of getting four heads with seven coin tosses can be calculated using the binomial probability formula.
Step-by-step explanation:
The probability of finding four heads with the binomial probability formula on seven tosses of a coin can be calculated using the combination formula. The formula is given by:
P(X=k) = C(n, k) * p^k * (1-p)^(n-k)
Where:
- P(X=k) is the probability of getting exactly k successes (in this case, 4 heads)
- C(n, k) is the combination of n objects taken k at a time
- p is the probability of getting a head on a single toss
- n is the number of tosses
Using the formula and substituting the values, we get:
P(X=4) = C(7, 4) * 0.5^4 * (1-0.5)^(7-4)
Calculating this probability will give you the answer.
