Explanation:
well, what do we expect in theory ?
a coin has a 50/50 chance for beads or tails. so, a probability of 1/2 for either one.
the probability for a survival number in a die is 1/6.
remember, the probability is always desired results over total possible results.
so, the combination is a simple multiplication.
the probability to get a certain side of the coin AND a certain number on the die is
1/2 × 1/6 = 1/12
so, this is what we would expect in theory : every combination happens in 1/12 of all cases.
now, what do we see in our practical experiment ?
there were 24 events (so, the total possible results are 24).
how many of them had heads and a 3 (the desired results) ?
there was only 1 result (in fact, there was only one 3 independently from the coin result, which is surprisingly low for 24 rolls of a die).
so, our experiment shows us a ratio or experimental probability of
1/24
for the desired result of heads with a 3 on the die.
we expected to get a ratio of
1/12 = 2/24
so, in reality, we got 1/24 less than theoretically expected.
