If you toss a coin 10 times and get heads 7 times what is the probability?
7/10
Toin coss Probabilty Question?
Can you PLEASE help me with this problem:Suppose a fair coin is flipped twice and the following payoffs are assigned to each of the 4 possible outcomes: H-H:win20; H-T: win 9; T-H:lose 7; T-T: lose 16what is the ecepected value of the gamble?What is the probablity of each event?Is the gamble fair?
What is experimental and theoretical probability?
They are just used to make equations and make more things like more equations and estimates!Theoretical Probability: P(event) the ratio of the number of favorable outcomes to the number of possible outcomes, written as a ratio.example: number of favorable outcomes over number of possible outcomesAmelynn is hungry, so she gets out a bowl and puts in 2 red jelly beans, 3 blue jelly beans, 12 pink jelly beans, and 3 yellow jelly beans. Amelynn likes the pink ones the best. What is the theoretical possibility of her getting a pink jelly bean?Answer: 12 over 20. (or 3 over 5 [simplest form])Explanation: Amelynn put 20 jelly beans in the bowl. She wants the pink ones, andthere are 12 pink jelly beans, which are the favorable outcomes. There are 20 jelly beans, and these are the possible outcomes. This means that it is 12 over 20. You might have to put this in simplest form as well. also this is 60% total.******************************************************************************************Experimental Probability: The number of times the outcome occurs compared to the total number of trials.example: number of favorable outcomes over total number of trials.Amelynn is flipping a coin. She finished the task one time, then did it again. Here are her results: heads: three times and tails: seven times. What is the experimental probability of the coin landing on heads?Answer: 3/10Explanation: Amelynn flipped the coin a total of 10 times, getting heads 3 times. Therefore, the answer is: 3/10 or 30%Theoretical probability ... a coin has 2 sides so the theoretical probability of flipping a coin and getting heads is 1/2.Experimental probability... flip a coin 10 time and you get 7 heads so the experimental probability of getting heads is 7/10
When a coin is tossed 10 times in a row what is the probability that heads comes up at least 7 times?
7/10
You toss a coin 10 times what is the probability of getting heads 7 time?
7/10
What is the probability of flipping a coin 7 times?
The probability is 1. I have flipped a coin a lot more than 7 times.
A fair coin is flipped three times what is the probability that the coin lands heads each time?
7/8
What is the probability of getting heads at least once if a fair coin is flipped three times?
7/8
If a coin is flipped 7 times what is the probability of landing on all tails?
each time you flip the coin, probability to end on either side is 50% (or 0.5) (we disregard landing on the side). So, to land on the same side 7 times, it is: 0.5^7
What is the probibility of getting one head if a coin is flipped three times?
It depends on whether you mean exactly one head or at least one head. There are 8 possible outcomes: TTT, TTH, THH, HHH, HHT, HTT, HTH, THT For at least one head, the probability is 7/8, for exactly one head, the probability is 3/8.
If you know that 7 times 8 equals 56how can you use communicative property of multiplication to find the product of 8 times 7?
You could use it because it shows that its just 7 times 8 flipped!
If you toss a coin 8 times there are 256 possible outcomes so how many of these outcomes have exactly 3 heads?
The number is 8!/[3!(8-3)!] where n! = 1*2*3*...*n ie 8*7*6/(3*2*1) = 56
Probability to get exactly 2 heads when flipping a coin 3 times knowing that you get at least one head?
Okay, lets write out the possible outcomes when flipping a coin 3 times: HHH, HHT, HTH, THH, TTH,THT,HTT,TTT That constitures 8 scenarios in which the coin can fall over a 3 flip trial. Now, it is known that you got "at least one head" so therefore we can rule out the no head scenario (TTT) which leaves us with 7. Of those 7 times, how many times does it fall heads exactly twice? Well, we have HHT,HTH,THH. From this you can say that it there are 3 possible outcomes in which you get exactly two heads given that you get at least one head. 3/7.
If you toss a coin 10 times and get heads 7 times what is the probability?
7/10
A coin is flipped seven times What is the probability that the outcome is other than all seven heads?
That's the same as the total probability (1) minus the probability of seven heads. So: 1 - (1/2)7 = 127/128
