number of heads, statistically would be 2.
Explanation:
so if one coin is tossed, you have a 1 in 2 chance of getting heads.
if four coins are tossed you have the possibility for heads/tails for each coin.
coin 1: Heads / Tails
coin 2: Heads / Tails
coin 3: Heads / Tails
coin 4: Heads / Tails
we can find the outcome using this formula
Probability(P) of an outcome = (Total number of desired outcomes) over (total number of possible outcomes)
in this case, Probability for number of HEADS =
4 coins flipped, each with two possible outcomes gives your total of 8 outcomes, with only 4 of those being the desired HEADS so you get 4/8 and simplify down.
