Question

When a fair coin was tossed ten times, it landed heads up the first seven times. What is the probability that on the eighth toss the coin will land with tails up?

Answer 1

Answer:

24.6%

Step-by-step explanation:

Number of possible outcomes = 2^10 = 1,024. Number of ways you can get exactly 5 heads is (10*9*8*7*6)/(1*2*3*4*5) = 252. Probability of getting exactly 5 heads = 252/1,024 = 24.6%

Answer 2

Answer:

Step-by-step explanation:

Number of possible outcomes = 2^10 = 1,024. Number of ways you can get exactly 5 heads is (10*9*8*7*6)/(1*2*3*4*5) = 252. Probability of getting exactly 5 heads = 252/1,024 = 24.6%
