Probability is given as Desired Outcomes divided by total number of outcomes.
For the probability of picking a vowel, desired outcomes are : a,e,i,o,u (5)
Total no. of outcomes is the entire alphabet set from a to z (26)
Hence, the required probabilty is 5/26
Assuming then that there are 100 numbers, 1-100, the probability of the number 23 being randomly picked out of 100 is: 1/100 or 0.01.
The word 'probability' has 11 letters and 5 of them are vowels (including the 'y'). Therefore the probability of picking a vowel is 5/11.
The probability of a single point being chosen is 0.The probability of a single point being chosen is 0.The probability of a single point being chosen is 0.The probability of a single point being chosen is 0.
1- P(identical) - P(fraternal) =1-0.004-0.023 =0.973 The probability of being a identical or fraternal twin plus the probability of not being a twin has to add to 1. so 1- probability of being twins=probability of not being a twin ;-)
Every member in the population has the same probability of being in the sample.Or, equivalently, every set of the given sample size has the same probability of being selected.
4/11
As there are no 12 cards in a standard pack the probability is zero.

A type of unit sampling where it is not known which of the units will be picked to be sampled, and where some of the units have a zero probability of being chosen.
1- P(identical) - P(fraternal) =1-0.004-0.023 =0.973 The probability of being a identical or fraternal twin plus the probability of not being a twin has to add to 1. so 1- probability of being twins=probability of not being a twin ;-)
Since 49 is a composite, the answer is 0.
Every member in the population has the same probability of being in the sample.Or, equivalently, every set of the given sample size has the same probability of being selected.
The probability that all will be graduates will be 5/20 x 4/19 x 3/18. This equals 0.0087719, or 0.877% The probability of at least one being a graduate is 1 minus the probability of none being graduates. That's 1-(15/20 x 14/19 x 13/18) = 1 - 0.39912280701754385964912280701754 = 0.600877 =60% Thus the probability of having at least one graduate is 60%
This question is not very well phrased - it is not clear if you want an actual random name, eg:QuinceoterusA name that is random (weird) and quinceoterus is a weird nameorA name that is randomHannahbecause Hannah is not a weird name, but it is a random name, in the sense of random being any name, just one random one picked out, not being weird or anythingorYou COULD be talking about what is a random name, as in what is the definition of a random name, therefore, the definition of a random name isa name which is picked at random.So. There.
There are eight different letters in 'mathematics' - a, c, e, h, i, m, s and t. Since there are 26 letters in the alphabet, the chance of a randomly chosen one being a letter that's in mathematics is 8/26, or 4/13.
