If you toss eight coins, there are 256 (28) different outcomes.
around 45
If you toss them enough times, the probability is 1. For just one toss the probability is 1/4.
It is 0.00540 approx.
you toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one head?
If you toss eight coins, there are 256 (28) different outcomes.
If we toss three coins 240 times, how many times can we expect the coins to have three tails showing?
If you toss the coins once only, it is 1/4.
around 45
There are three possibilities, Heads, Tails and stand on edge
15

Well, honey, if we're talking about South African 1 rand coins, which have a diameter of about 20 mm, you could fit approximately 375 coins into a 2-liter Coke bottle. But who's got time to count all those coins? Just toss 'em in and see how many you can squeeze in there!
you toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one head?
is it 50% or 100% dang, i just confused myself. what if you toss 3 coins all at the same time... what's the probability of getting a head then, is it > 100% ? Doh!
The expected number is 3750.
