What is probability 2 girls are chosen if 10 students are girls and 15 are boys?
The probability of choosing 2 girls at random from group of 25 students of which10 are girls and 15 are boys is:P( 2 girls) = (10/25)∙(9/24) = 3/20 = 0.15 = 15%

From a standard deck what is the probability of picking either an ace or a king?
On one random draw, the probability is 2/13.
What is the probability of a woman giving birth to 6 daughters in a row?
Theoretically we might imagine that the probability that a woman would give birth to a daughter would be 1/2. With this assumption then the probability would be 1/2 x 1/2 x 1/2 x 1/2 x 1/2 x 1/2 = (1/2)6 = 1/26 = 1/64However, there are other considerations:The ratio of boys to girls at birth varies by country. (The most boys to girls occurs in-wait for it-Liechtenstein.) This means that the probability of giving birth to six girls in a row in some country would be less, in others maybe more.If a women gave birth to three girls in a row then you would have some grounds for suspecting that there could be something about her and her partner that favours the conceptions of girls. If this were true then the probability of there being six girls in a row would be much higher.

What is the probability that a family with 4 children has at least 2 girls?
Assuming that boys and girls are equally likely, it is 11/16.
What is the difference between a probability and a fraction?
The probability is always a fraction except when it is 0 or 1. If a probability = 1 then it will definitely happen. If the probability is 0 then it will not happen. If you toss a fair coin the probability of heads is 1/2, and the probability of tails is 1/2. These fractions are representations of the probabilities. Not all fractions are representative of probabilities. Fractions can be used to represent a portion of a whole. Like what portion of a class is boys, and what portion is girls: If there are 8 boys and 7 girls, then the 8/15 of the class is boys, and 7/15 of the class is girls.

3-7
What is theoretical probability of picking 2 squared numbers out of 15?
The answer depends on whether the first number is replaced before picking the second. If not, the probability is 0.029
What is the probability of picking a vowel from the word total?
2 in 5
What is the probality of picking 23 of hearts in a deck of cards?
The probability of picking a 23 of hearts in a standard 52 card deck of cards is zero, because there is no 23 of hearts. If you meant to ask about the probability of picking a 2 or a 3 of hearts, then the probability is 2 in 52, or 1 in 26, or about 0.03846.
What is the probability a girl is chosen if 15 students are girls and 10 students are boys?
The ratio of girls to total students is 15:25, or 3:5. Three out of five students are girls so there would be a 60% probability that a girl would be chosen; a 2 out of 5 chance, or 40% probability that a boy would be chosen.
From a standard deck what is the probability of picking either an ace or a king?
On one random draw, the probability is 2/13.
