When three coins are tossed how many times out of 100 would you expect the result to be either three heads or three tails?

Answer 1

Each coin has 2 outcomes. Either being heads or tails. Take the outcome of each coin to the root of the number of coins.

(1/2)^3 = .125 = 12.5% or a 1 in 8 chance.

Take .125 and times it by 100 to get the probability out off 100 times.

.125 x 100 = .125 which = 12.5%= 1 in 8 chance
