A die normally has 6 sides numbered 1 through 6. The probability of you landing on ANY number is 1:6, or you have a 1 in 6 chance of landing a 3.
Probability of a spinner of 20 landing on 5 is 1/20.
The probability is 1/42.

The probability is one in four, or 25%.
The probability is 3/7.
The probability is 5/9.

The probability of landing on heads each time a fair coin is flipped, is 1/2.Assuming that the question was supposed to be:"What is the probability of landing on heads twice in a row?"To calculate compound probabilities like this, we first have to work out the probability of landing on heads each time, and then multiply these two probabilities to get a compound probability.1/2 x 1/2 = 1/4So the probability of landing on heads twice in a row = 1/4 (for a fair coin)
Assuming that it is a regular shaped spinner, the probability is 1/6*1/6 = 1/36

The probability is 6 in 12, or 1 in 2.
The probability that both coins are heads is the probability of one coin landing heads multiplied by the probability of the second coin landing heads: (.5) * (.5) = .25 or (1/2) * (1/2) = 1/4
