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 ;-)
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%
4/11
The statement about the probability of selecting the letter 'z' from the alphabet being 126 is incorrect. The probability of selecting any one specific letter from the 26 letters of the English alphabet is 1/26, not 126. Therefore, the probability of selecting 'z' is approximately 0.0385, or about 3.85%.
As there are no 12 cards in a standard pack the probability is zero.
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.
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 ;-)

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.

Since 49 is a composite, the answer is 0.
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.
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.
