The answer is theoretical; the result is based on the number of possible outcomes. When you toss a coin, there are two possible outcomes - heads or tails. The probability of getting heads on a single toss is 1/2 or 0.5. Therefore, the probability of getting heads on 15 tosses can be calculated using the binomial probability distribution formula:
P(X = k) = nCk * p^k * (1-p)^(n-k)
Where:
n = 15 (number of trials)
k = number of successes (getting heads)
p = probability of getting heads (2/5 = 0.4)
P(X = 7) = 15C7 * 0.4^7 * (1-0.4)^(15-7)
P(X = 7) = 0.174
Therefore, the probability of getting exactly 7 heads in 15 tosses of a coin with a probability of 2/5 (0.4) of getting heads on a single toss is 0.174 or approximately 17.4%.
