What is the probability of obtaining a 3 and a tail?

What is the probability of obtaining a 3 and a tail?

1/8
Answer: The probability of flipping a coin three times and getting 3 tails is 1/8. Let’s solve this step by step. Explanation: Let us mark H for Heads and T for Tails.

What is the probability of obtaining an odd number and a head?

Find the probability of getting a head and an odd number. The answer is 14. My reasoning is that rolling an odd number is 12, and tossing a coin on heads is 12. So 0.5×0.5 = 14.

What is the probability of obtaining an even number and a tail?

Explanation: The coin is fair, the probabilities of getting a head and a tail are equal to 12 . The probability of getting an even number on a die is 36=12 because among 6 results there are 3 even numbers.

What is the probability of obtaining a head and a 2?

From the diagram, you can see that there are 12 possible outcomes and getting a “2 Heads” is only one of the 12; hence the probability is 1/12.

What is the probability of rolling a 3 on a fair dice?

Two (6-sided) dice roll probability table

Roll a… Probability
3 3/36 (8.333\%)
4 6/36 (16.667\%)
5 10/36 (27.778\%)
6 15/36 (41.667\%)

What is the probability that he rolls an odd number and flips a head on the coin?

The probability of flipping heads is 1/2. The probability of rolling an odd number and then flipping heads is (1/2)(1/2)=1/4 using the product principal.

What is the probability of flipping heads and rolling an odd number?

According to probability formula, p(A) = favorable number of outcomes/all possible outcomes in the sample space = 3/12 = 1/4 =0.25 or 25\%. So 25\% chances are there if getting one head and an odd number.

What is the probability of getting an even and head number?

512/210
So the probability of getting an even number of heads is 512/210 and that turns out to be exactly ½. In- deed, 512 is equal to 29 and that’s half of 210, and the game is fair!

What is the probability of rolling a 2 and flipping heads?

The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25. A visual representation of the toss of two coins. The Product Rule is evident from the visual representation of all possible outcomes of tossing two coins shown above. The probability of getting heads on the toss of a coin is 0.5.

What is the probability of getting a tail on a coin?

The probability of getting a tail (assuming it’s an unbiased coin) is 1/2. Therefore, the probability of both events ocurring would be: P (odd number & tail) = P (odd number) * P (tail) = 3/6 * 1/2 = 3/12 = 1/4. where P:= probability Originally Answered: Larry rolls a fair dice and flips a fair coin.

What is the probability of rolling a fair die and getting heads?

Using the idea that there is a 50\% probability that it will come up heads is ONLY VALID IF and ONLY IF the “fair” coin is tossed an INFINITE number of times. The same is equally true for rolling a “fair” die and getting an odd number.

Why do people roll odd numbers when rolling fair dice?

The same is equally true for rolling a “fair” die and getting an odd number. This is why people lose a LOT of money on Casino Games, because they believe that if it come up heads 5 times in a row, it will “probably” come up tails next or soon there after.

What is the probability of getting heads on a single flip?

B is the event of getting Heads on a single flip of a fair coin. And its probability is one half. When two events are independent then the probability of both of them happening is simply the product of the probability of each. In this problem A and B are independent so the so the probability of both happening, P ( A & B) is given by
