# Three coins are tossed what is the probability of getting at most one head

• This is because the possibility of obtaining a Head in a coin toss is as likely as obtaining a tail, that is, 50%. So when you toss one coin, there are only two possibilities – a head (H) or a tail (L). However, what if you want to toss 2 coins simultaneously? Or say 3, 4 or 5 coins?
Sep 28, 2009 · 2. rowdy3 said: more than 3 heads. odds of 1 coin landing on tails 1/2. odds of 2 coins landing on tails 1/2 * 1/2 = 1/4. odds of 3 coins tails 1/2 * 1/2 * 1/2 = 1/8. odds of 4 coins tails 1/2 * 1/2 * 1/2* 1/2 = 1/16. not quite - i would re-write what you have as. T - odds of 1 st coin landing on tails 1/2.

Three fair coins are tossed together. Sample spade = {HHH, HHT, HTH, HTT, THH, THT, TTH, TTT} n(S) = 8. Let C be the event of getting atmost one head
• Coin Toss Probability Calculator . When a coin is tossed, there lie two possible outcomes i.e head or tail. If two coins are flipped, it can be two heads, two tails, or a head and a tail. The number of possible outcomes gets greater with the increased number of coins. Most coins have probabilities that are nearly equal to 1/2.

For n = 1, the probability to reach the ﬁrst head in M ﬂips is the probability of M−1 tails and one head, hence p1(M) = pM. The average number of ﬂips until the ﬁrst head is P∞ k=0(k + 1)(1− p)kp = 1/p. The probability distribution p1(M) is shown for a fair coin (p = 1/2) in the ﬁrst ﬁgure on the next page.

The first sheet deals with the experiment when 10 coins are tossed when the probability of getting a head can be altered. The probability of getting a particular number of heads is shown in a table (alongside the cumulative probability) and in a bar chart. The second interactive sheet deals with a similar experiment when 20 coins are tossed.

If three coins are tossed simultaneously at random, find the probability of: (i) getting three heads, (ii) getting two heads, (iii) getting one head, (iv) getting no head. Solution: Total number of trials = 250. Number of times three heads appeared = 70. Number of times two heads appeared = 55. Number of times one head appeared = 75.

Ex 16.3, 8 Three coins are tossed once. Find the probability of getting 3 heads If 3 coins are tossed various combination possible are S = {HHH, HHT, HTH, THH, HTT, THT, TTH, TTT} n(S) = 23= 8 Let A be the event of getting 3 head A = {HHH} ∴ n(A) = 1 Probability of 3 heads = P(A)

\probability" is intended to be the probability that the corresponding outcome occurs (see Section 4.4.4). In sport, coins are tossed to decide which end of the ground a team is to defend, or who is going to go into bat ﬂrst. It is quite common to call the outcome after the coin has been tossed, but before it has fallen. Even with a
