What is the probability of getting anything but one head and two tails?

Only one of the eight outcomes represents the event of 0 heads, so its probability is 1/8. Three of the eight outcomes represent the event of 1 head (and 2 tails): HTT, THT, and TTH. This event therefore has a probability of 3/8.

When three coins are tossed what is the probability of getting one head or two tails?

3/8
What is the probability of two heads and one tail? Summary: The Probability of getting two heads and one tails in the toss of three coins simultaneously is 3/8 or 0.375.

What is the probability of getting at least one head when tossing three coins?

If you flip a coin three times the chance of getting at least one head is 87.5\%.

What is the probability of getting exactly one tails when three coins are tossed?

Probability of getting at least 1 tail in 3 coin toss is 1−18=78 .

What is the probability of tossing 2 coins?

The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25. The second useful rule is the Sum Rule.

What is probability of getting one tail?

We have to find the probability of getting at least one tail. The probability of getting at least one tail is equal to one minus the probability of all heads. Therefore, the probability of getting at least one tail is 1023 / 1024.

What is the probability of getting two heads when 3 coins are tossed?

When 3 coins are tossed, the possible outcomes are HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. (i) Let E 1 denotes the event of getting all tails. Hence the required probability is ⅛. (ii) Let E 2 denotes the event of getting two heads. Hence the required probability is ⅜.

When 3 unbiased coins are tossed once what are the possible outcomes?

When 3 unbiased coins are tossed once. When 3 coins are tossed, the possible outcomes are HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. (i) Let E 1 denotes the event of getting all tails. Hence the required probability is ⅛. (ii) Let E 2 denotes the event of getting two heads.

How many times can you toss 3 coins at once?

When you toss 3 coins simultaneously, the possibility of outcomes are (HHT), or (TTH) or (HHH) or (THT) or (THH) or (HTH) or (HTT) or (TTT), where H is called the heads and T is called the tails. Therefore, the total number of toss for outcome = 2 3 =8.

What is the required probability of getting one head?

Hence the required probability is 7/8. (iv) Let E 4 denotes the event of getting one head. Hence the required probability is 3/8. Example 2: In an experiment, three coins are tossed simultaneously at random 250 times.
