Prob(at least 4 heads) = Prob(4 heads) + Prob(5 heads) = 5/32 + 1/32 = 6/32 = 3/16
There is no probability. Sorry.
The probability is 0.0322
The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8
The probability of this is 50%. 2/4
If they are normal dice, the probability is 0.
It is 0.3438
Since each event is independent, the probability remains at 0.5.
If the events can be considered independent then the probability is (0.7)4 = 0.24 approx.
you are looking for the probability of getting one tail, two,......., and six this equivalent to saying 1 - the probability of not getting any tails (or getting 6 heads = (1/2)^6). P(X>=1) = 1 - (1/2)^6=
The probability of getting a heads on the first flip is 1/2. Similarly, the probability on each subsequent flip is 1/2, since they are independent events. The probability of several independent events happening together is the product of their individual probabilities.
The probability of getting a head is 1/2 and if you toss it 4 times, the probability of 4 heads is (1/2)^4=1/16 since the tosses are independent events.
Well they are independent events so it is the probability of getting a correct answer multiplied by the probability of getting a correct answer on the second question. Short Answer: 1/5 times 1/5=1/25
Yes. Independent events can exist in reality. Dependent events means that one event has had an effect on the other. For instance, if we look at the probability of someone going to the shops, and the probability of them buying an apple, the latter is clearly dependent on the former. Independent events are simply events that don't have this connection. The probability of one does not influence or predict the probability of the other. For instance, if I studied the probability of you going to see a film on a particular day, and the probability of someone in China getting a hole in one in golf, these are very clearly independent events.
If it is a fair die and rolled fairly, the two events are independent so that the probability is 1/6.
25% or 0.25 Probability of one tail is 0.50. Since two tails are independent events, the probability is 0.5 x 0.5 = 0.25
You must first look at all possible outcomes:1, 2, 3, 4, 5, 6Then, reread the question that is being asked:A dice is rolled 6 times, what is the probability of getting atleast a 3.You should underline the important parts of the question and then preceed to answering:When the question states, atleast a 3, it means to say the minimum result of 3 (as in 3, 4, 5 and 6)The math:(Outcomes that satisfy the statement)/(Total outcomes) * 100We multiply by 100 to receive a percentage.4/6 * 100 = 66.67%The answer:The probability of getting atleast a 3 when a dice is rolled 6 times is 66.67%.
This depends entirely on the genotype of the parents. The probability of getting a specific genotype is the probability of getting the correct allele from mother (1/2) multiplied by the probability of getting the correct allele from father (1/2) multiplied by the number of ways this can occur. The probability of getting a phenotype, if the phenotype is dominant, is the sum of the probability of getting two dominant alleles, and the probability of getting one dominant allele. If the phenotype is recessive, the probability is equal to the probability of getting two recessive alleles.
