To find the probability that Hanif will lose the game, we first need to determine the total possible outcomes when tossing a coin three times.

Total Outcomes

Each toss of the coin has 2 possible results: heads (H) or tails (T). Therefore, for three tosses, the total number of outcomes can be calculated as:

  • 2 (for the first toss) × 2 (for the second toss) × 2 (for the third toss) = 23 = 8

Winning Outcomes

Hanif wins if all tosses are the same. The winning outcomes are:

  • HHH (three heads)
  • TTT (three tails)

Thus, there are 2 winning outcomes.

Losing Outcomes

To find the losing outcomes, we subtract the winning outcomes from the total outcomes:

  • Total outcomes: 8
  • Winning outcomes: 2
  • Losing outcomes: 8 - 2 = 6

Calculating Probability

The probability that Hanif will lose the game is the number of losing outcomes divided by the total outcomes:

Probability of losing = Number of losing outcomes / Total outcomes

Probability of losing = 6 / 8 = 3 / 4

Final Result

Therefore, the probability that Hanif will lose the game is 3/4 or 75%.
