Maria is tossing a fair coin. She tosses the coin ten times and it lands on heads eight times. If Maria tosses the coin an eleventh time, what is the probability that it will land on heads?

A) 1/5
B) 1/2
C) 4/5
D) 3/2

Asked by RyanTheMathMaster

Answer (2)

The correct answer is B. The eleventh toss of a coin is independent from previous tosses. So regardless of what happened before, the chance to get heads is always 1/2.

The probability that the coin will land on heads during the eleventh toss is 2 1 ​ or 50%. This is because each toss is an independent event, meaning past results do not change this probability. The chosen answer is B) 2 1 ​ .
