What is the probability of tossing four coins and getting four heads if the first two tosses are heads?
The conditional probability is 1/4.
What is the probability of tossing two coins and getting heads on both?
1/2
What is the probability of tossing 3 coins and getting 3 tails?
It is (1/2)3 = 1/8
You are tossing three coins and want to determine the probability for getting at least one head?
Pr(At least one head in three tosses) = 1 - Pr(No heads in three tosses) = 1 - Pr(Three tails in three tosses) = 1 - (1/2)*(1/2)*(1/2) = 1 - 1/8 = 7/8 or 0.875 or 87.5%
What is the probability of tossing two coins that are different?
The probability of tossing two coins that are different is 1 in 2, or 0.5.The probability of tossing something on the first coin is 1. The probability of not matching that on the second coin is 0.5. Multiply 1 and 0.5 together, and you get 0.5.
What is the probability of tossing four coins and getting four heads if the first two tosses are heads?
The conditional probability is 1/4.

0.1222...
What is the probability of getting 2 heads when 2 coins are tossed?
The probability of tossing two heads in two coins is 0.25.
When tossing 2 coins the probability of getting exactly 1 tail is .?
0.5
What is the probability of tossing two coins and getting heads on both?
1/2
Probability of getting 1 head tossing two coins?
By tossing two coins the possible outcomes are:H & HH & TT & HT & TThus the probability of getting exactly 1 head is 2 out 4 or 50%. If the question was what is the probability of getting at least 1 head then the probability is 3 out of 4 or 75%
What is the probability of tossing seven coins at one time and having 7 of them come up heads?
The probability would be once in 128 attempts. You don't have to toss seven coins simultaneously. the 7 tosses just have to be independent of one another.
When tossing 2 coins the probability of getting exactly 1 tail is one fourth?
No. It is 1/2.
What is the probability of tossing 3 coins and getting 3 tails?
It is (1/2)3 = 1/8

The probability of tossing two coins that are different is 1 in 2, or 0.5.The probability of tossing something on the first coin is 1. The probability of not matching that on the second coin is 0.5. Multiply 1 and 0.5 together, and you get 0.5.
What is the probability of tossing four coins and getting tails on all four?
Assuming it is a fair coin, the probability is 1/24 = 1/16.
