3 out of 8
There are 4 events: 3 heads, 2 heads 1 tail, 1 head 2 tails, and 3 tails.
The probability of tossing two heads in two coins is 0.25.
2 heads and 2 tails
Coins with 2 heads or 2 tails are novelty coins created to be sold for profit. They have no value other than the worth of the metals in them.
2/6=1/3
1/4 if they are tossed only once.
1/2
possible
lets get some facts odds of head on 1 coin 50% or evens odds of no head 50% or evens the possible results vary from 1 coin to 2 coins. 1 coin has 2 results heads or tails 2 coins have 4 results. heads heads, tails tails, tails heads, heads tails. each outcome has a probability of 25%. for the question we remove the heads and tail probability and we have 2 outcomes with heads and one without. so 2 to 1 chance or 33.3333 recuring chance.

The probability is 3/8 = 0.375
The expected value is the number of tosses times the probability of tails, so: E(number of tails) = 52 * 1/2 = 52/2 = 26
2/9
The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.
There are 4 events: 3 heads, 2 heads 1 tail, 1 head 2 tails, and 3 tails.
Less. The more times the coin is tossed, the more likely it will reflect the actual odds of .5 heads and .5 tails.
Half the time they will be the same, half the time they will be different. Half of the time that they're the same they will be heads, half the time they are the same they will be tails. It's your homework, YOU figure it out. The way I figure it. There are four options: 1) heads / heads 2) heads / tails 3) tails / heads 4) tails / tails By process of chance, one out of four times both coins will be heads/heads. Therefore 780/4 = 195 times.
