The expected value is the number of tosses times the probability of tails, so:
E(number of tails) = 52 * 1/2 = 52/2 = 26
52/2=26
The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.
If we toss three coins 240 times, how many times can we expect the coins to have three tails showing?
there could be five possible outcomes: t= tails h= heads t t t t 4 tails t t t h 3 tails 1 head t t h h 2 tails 2 heads t h h h 1 tail 3 heads h h h h 4 heads
There are two answers to this question. If it can only land on heads or tails up, then there is a 50% chance ( or half a chance) it will land heads up, but that's not necessarily true. But, if it can land on heads, tails, or sides, then there is a 16% chance it will land tails up.
If you toss a fair coin 250 times , about how many times should it land on tails?
The answer depends on how many coins were tossed.
1/4
The answer depends on the experiment: how many coins are tossed, how often, how many dice are rolled, how often.
The odds that a tossed coin will land tails side down remain one in two no matter how many times the coin has previously been tossed.

The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.
There are 4 events: 3 heads, 2 heads 1 tail, 1 head 2 tails, and 3 tails.
Eight.
If you know which coin is which, there are 16possible outcomes.If you're only counting the number of Heads and Tails, there are 5 .
Two
Out of the 16 possible outcomes for a coin tossed four times, 4 of them result in 3 Tails & 1 Head. They are: TTTH, TTHT, THTT, and HTTT.
