if a fair coin is tossed 3 times, what is the probability of getting 3 tails?
1 1/3
2 3/3
3 3/8
4 1/8
is it 3/3.... coz all 3 could be tail also ....am i right?
plz help me
toss the coin once, what is the prob of getting heads? 1/2 right?
now does the coin have a memory of what happened last time?
so toss it again.
What is the prob this time? Still 1/2, right?
now now you have 1/2*1/2 of two in a row.
What would it be 3 times in a row???
BTW, a prob of 3/3 is a prob of 1, which means "absolute certainty"
In that case you should be willing to bet $ 1 million that you will get 3 heads in 3 tosses. What do you think??
thanks
No, the correct answer is option 4: 1/8.
To calculate the probability of getting 3 tails when a fair coin is tossed 3 times, we need to determine the probability of getting a tail on each individual toss and multiply them together.
Since the coin is fair, the probability of getting a tail on a single toss is 1/2 (there are 2 equally likely outcomes - heads or tails - and we want only one of them).
To find the probability of getting 3 tails in a row, we need to multiply the individual probabilities of getting tails on each toss. Since there are 3 tosses, we multiply 1/2 by itself 3 times:
(1/2) * (1/2) * (1/2) = 1/8
Therefore, the probability of getting 3 tails is 1/8, which corresponds to option 4.
