What is the probability of the coin landing on heads?
The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
What is the probability of getting a head on the coin and the number 6 on the die?
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 getting a heads on the coin and the number 3 on the number cube?
If we assume a fair coin and a fair number cube, the chances of hitting heads on a coin is 50\% (1/2) and the chance of rolling a 1, 3, or 4 is also 50\% (1/2). Therefore we multiply these probabilities together to get 25\%, or 1/4.
What is the probability of rolling an odd number on a number cube and tossing tails on a coin?
So the answer is 1/4. You can use a tree to better understand probabilities. The possible outcomes are (H,1),(H,3) and (H,5) where H is the head when a coin is tossed and 1,3 and 5 are the odd outcomes of rolling a cube. Hence, required probability is 1/2 x 1/6 + 1/2 x 1/6 + 1/2 x 1/6 = 1/4.
What is the probability of a coin landing heads up on the next coin toss assuming you had just seen three consecutive coin tosses in which the coin landed heads up?
Three flips of a fair coin Suppose you have a fair coin: this means it has a 50\% chance of landing heads up and a 50\% chance of landing tails up. Suppose you flip it three times and these flips are independent. What is the probability that it lands heads up, then tails up, then heads up? So the answer is 1/8, or 12.5\%.
What is the probability of getting a head on the coin and the number 1 on the die?
Under the standard assumptions (fair coin, unbiased 6-sided die with 6 sides numbered 1-6), the probability of getting a head with the coin is 1/2 and the probability of getting an even number on the die is likewise 1/2 (I assume you’re talking about only one roll).
What is the probability of getting a 5 then tails?
Assuming the coin is fair, the probability of tossing tails is 12 (because there are two, equally likely options). Therefore, to get the probability of rolling a 5 AND tossing tails, you multiply (16) by (12) , and get the answer (112) .
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.
