1. A coin is tossed three times. Solution:- Since either coin can turn up Head (H) or Tail (T) If the number on the die is odd, the coin is tossed twice. Write the sample space for this experiment. 15. A coin is tossed. If it shows a tail, we draw a ball from a box which contains 2 red and 3 black balls.
Let's say we have 10 flips, the probability of at least one head in 10 flips-- well, we use the same idea. This is going to be equal to the probability of not all tails in 10 flips. So we're just saying the probability of not getting all of the flips going to be tail. All of the flips is tails-- not all tails in 10 flips.
An illustration of probability can be found in looking at the probability of getting a head when tossing a fair coin. The expected frequency of getting a head is 1, the total frequency is 2 (1 head and 1 tail), and the probability is ½. The probability of rolling a six on one die is 1/6.
