When a coin is tossed What are the 2 possible outcomes?
When a fair coin is tossed then there are two possible outcomes: H(head), T(tail).
When a coin is tossed 4 are outcomes True or false?
N=4: There is only one possible outcome that gives 4 heads, namely when each flip results in a head. The probability is therefore 1/16.
What is the probability exactly 2 heads when tossing a coin thrice?
Answer: If you flip a coin 3 times, the probability of getting at least 2 heads is 1/2.
What is the probability of getting 3 heads in 8 tosses?
The probability of getting exactly 3 heads out of 8 with a fair coin would be 8C3 / 2^8 = 56 / 256 = . 21875.
What is the probability of an unfair coin being tossed?
An unfair coin is tossed 3 times. The probability of heads is p = 0.2, and the number of heads is denoted by X. What is the value of E [ X]?
What is the total number of outcomes when tossing three coins?
We know that when a coin is tossed, the outcomes are head or tail. We can represent head by H and tail by T. Now consider an experiment of tossing three coins simultaneously. The possible outcomes will be HHH, TTT, HTT, THT, TTH, THH, HTH, HHT. So the total number of outcomes is 2 3 = 8.
What is the probability of flipping 3 coins and getting 12 heads?
Since I’m flipping 24 coins in total (3 coins 8 times), I expect 12 heads. Th Three coin flips, each with two outcomes, result in eight possibilities, each with probability 1/8 (1 over 2 to the third power). So let’s do this for the particular case of enumerating all the ways those three coins can appear.
What is the probability that the first or the second toss is heads?
Since you want the probability that the first or the second toss is heads, that means it could be HT, TH and even HH (since you mentioned that the first OR the second toss is head; it could be both heads as well!), but never TT. You realised if you summed up the probability values in bold; you would get a total of 1.00.
