If the toppings are picked at random, then the answer is 9/14.
To work out probability you have to know the number of possible options, and how many of those options meet the criteria. In this case there are 26 possible options (all the letters) and 21 that meet the criteria (21 non-vowels). The probability is the number that match divided by the total number possible. In this case it would be 21/26. This comes out to approximately 0.80769. Thus the probability that a letter picked at random is not a vowel is 0.80769
If a student is picked at random what is the probability that he/she received an A on his/her fina?
If only one person is picked at random then the probability is 1/16 = 0.0625
4/11
What is the probability that the letter P is picked when a letter is picked at random from the word STUPID!
The probability that a date picked at random is February 30th is zero, as there is no February 30th, even in leap years.
Pr(Both picked 3) = 1/16Pr(Both picked the same) = 1/4.
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 answer depends on how many cards are picked, whether they are picked at random, from what sort of pack, and whether or not cards are replaced before the next one is picked. The probability that a single card, picked at random from a regular 52 card deck is red, is 0.5
If the winning numbers are picked at random, the probability is 1 in 169911.
Two bags - 100 bags - The computation of probability is the same process - you take the number of desired results and divide by the number of possible results. The difference here is that the desired result sets do not intersect the possible result sets for the two bags, but the computation is the same - desired divided by possible.
