Possible outcomes per each toss = 6
Number of them that are not a 3 = 5
Probability of no 3 in one toss = 5/6.
Probability of no 3 in 5 tosses = (5/6) x (5/6) x (5/6) x (5/6) x (5/6) = 3,125/7,776 = 0.40188 = 40.19%(rounded)
The probability of tossing heads on all of the first six tosses of a fair coin is 0.56, or 0.015625. The probability of tossing heads on at least one of the first six tosses of a fair coin is 1 - 0.56, or 0.984375.
It is 1/8.
If you toss the die often enough then the probability of getting the sequence 2-2-1 is 1: a certainty. The probability of getting the result in the first three tosses is 1/216.
I don't know! I asked you!
The probability of getting five heads out of 10 tosses is the same as the probablity of getting five tales out of ten tosses. One. It will happen. When this happens, you will get zero information. In other words, this is the expected result.
The probability of tossing heads on all of the first six tosses of a fair coin is 0.56, or 0.015625. The probability of tossing heads on at least one of the first six tosses of a fair coin is 1 - 0.56, or 0.984375.
It is 0.5
It is 0.3438
1/16
In a large enough number of tosses, it is a certainty (probability = 1). In only the first three tosses, it is (0.5)3 = 0.125
If both tosses are fair, the probability of that outcome is one in four.
It is 1/8.
1 out of 12
If you toss the die often enough then the probability of getting the sequence 2-2-1 is 1: a certainty. The probability of getting the result in the first three tosses is 1/216.
The probablility of getting 2 tails in 4 tosses of a fair coin is most likely 50%, 2/4=1/2, or .50.
I don't know! I asked you!
If the coin is fair, the probability of getting all heads will decrease exponentially towards 0.
