Question

Four coins are tossed and the number of heads is counted?

Answer 1

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 = `4/8` which simplifies to `1/2` or 0.5 or 50%.

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.
