Probability

The probability of a certain event is a number expressing the likelihood that a specific event will occur, expressed as the ratio of the number of actual occurrences to the number of possible occurrences. In mathematics, it is a measure of how often an event will happen and is the basis of statistics.

If you flip a coin two times how many outcomes give you a head and a tail?

it depends on if you can ride a unicycle dressed as Hitler with one shoe and no sock on the other foot and one hand tied behind your back with a fish being juggled by the other hand and your tongue.

What is the probability that she will roll a number other than 1?

On a single toss of a six-sided die. The chance of rolling a one is 1/6, and the chance of not rolling a one is (1 - 1/6 = 5/6), or 83.333 %

Roberto has 200 coins and distributes them in such a way that each friend gets at least one coin and no two friends get the same number of coins what's the largest number of friends Roberto could have?

If Roberto has 200 coins and distributes them in such a way that each friend gets at least one coin, and no two friends get the same number of coins, the largest number of friends Roberto could have is 19.

This is a simple triangular function of a number.

1+2+3+4+5+6+7+8+9+10+11+12+13+14+15+16+17+18+19 = 190

At that point, Roberto only has 10 coins left, and he can not give them to anyone else without duplicating the amount two friends get.

A box contains identical cards on each card a letter of the English alphabet is printed.A card is selected at random from the box and not replaced and a second card is then selected. Find the probability that two cards selected(I) have vowels printed?

There are 26 letters in the English alphabet, of which 5 are vowels (a, e, i, o, u). Since each card is identical and there are 26 cards in the box, the probability of selecting any one card is 1/26.

To find the probability of selecting two cards with vowels printed, we need to use the concept of conditional probability. The probability of selecting a vowel on the first draw is 5/26, since there are 5 vowels in the box. After the first card is selected and not replaced, there are only 25 cards left in the box, of which 4 are vowels (since one vowel has already been selected). Therefore, the probability of selecting a vowel on the second draw, given that a vowel was selected on the first draw, is 4/25.

To find the probability of both events occurring (i.e., selecting two cards with vowels printed), we need to multiply the probabilities of each event together, since they are independent:

P(selecting a vowel on the first draw) x P(selecting a vowel on the second draw, given that a vowel was selected on the first draw) = (5/26) x (4/25)

Simplifying this expression, we get:

(5/26) x (4/25) = 20/650 = 2/65

Therefore, the probability of selecting two cards with vowels printed is 2/65
