Question

If a coin is fliped 10 times , What is the probability of 8 or more heads ? ​

Answer 1

Answer:

0.05 is the probability of getting 8 Heads in 10 tosses

Answer 2

Answer:

So the probability of getting at least 8 heads in 10 coin flips is 0.0547.

Step-by-step explanation:

You can calculate this by multiplying the probabilities of getting 8 heads in a row, 2 tails in a row, and the number of combinations containing 8 heads and 2 tails in 10 coin tosses.

P = [(0.5)^8 (0.5)^2] [10!/(8!2!)] = 0.044
