For a 6 sided die, each number 1 - 6 has equal probability. So, probability of rolling a 5 is 1/6.
The probability would be that of independently rolling a five once, multiplied by the same probability for a second time.The two rolls are treated independently with P(5) = probability of rolling a single '5' = 1/6.P(5,5) = Probability of rolling one 5 and then another 5, out of two rollsp(5,5)=p(5 AND 5)=p(5)*p(5)=(1/6)*(1/6)=1/36So it's 1/36, or 0.0278
Probability of a spinner of 20 landing on 5 is 1/20.
Probability of no heads = (0.5)^5 = 0.03125Probability of at least one head = 1 - probability of no heads = 1 - 0.03125 = 0.96875
the probability is 1 out of 6
