the 5 on the die would be 1/6 if the die has the numbers 1-6 on it because each number has an equal chance of being landed on. for tails on a coin it would be 1/2 because both sides have an equal chance of being landed on.

It is 0.5 becasue the events are (or should be) independent.

Assume the coin is fair, so there are equal amount of probabilities for the choices.There are two possible choices for a flip of a fair coin - either a head or a tail. The probability of getting a head is Â½. Similarly, the probability of getting a tail is Â½.Use Binomial to work out this problem. You should get:(5 choose 4)(Â½)4(Â½).(5 choose 4) indicates the total number of ways to obtain 4 tails in 5 flips.(Â½)4 indicates the probability of obtaining 4 tails.(Â½) indicates the probability of obtaining the remaining number of head.Therefore, the probability is 5/32.

Firstly, the probability when tossing a coin and getting a head or tail is 1/2, then rolling a die, there are 6 sides so the chance of rolling any number is 1/6, there are 2 chances of rolling greater than 4 ie 5 and 6, so the probability of rolling a 5 or 6 in 1/3, as these are independent events you multiply the probability getting a heads of tails, (1/2) by the probability of rolling a five or six, (1/3) which gives you 1/6 or 0.1666 recurring.

1/12 (1/6 chance of a 5 * 1/2 chance of getting tails)

Assume the coin is fair, so there are equal amount of probabilities for the choices.There are two possible choices for a flip of a fair coin - either a head or a tail. The probability of getting a head is ½. Similarly, the probability of getting a tail is ½.Use Binomial to work out this problem. You should get:(5 choose 4)(½)4(½).(5 choose 4) indicates the total number of ways to obtain 4 tails in 5 flips.(½)4 indicates the probability of obtaining 4 tails.(½) indicates the probability of obtaining the remaining number of head.Therefore, the probability is 5/32.

If it is a fair coin, the probability is exactly 50%. The coin has no memory of what it did in the last flip. ■

The probability is 1 out of 5

This is one of those cases where it is probably easier to think what is the probability of not doing it, then subtracting that from 1 to get the probability of doing it. To not get at least one head and one tail, you would have to get all heads or all tails. To get all heads, the probability is (1/2)5. To get all tails is the same probability; so double it to get the probability of either of those. 2(1/2)5=1/16. Subtract the 1/16 from 1 to get 15/16. Answer: 15/16
