Final answer:
The probability of flipping a coin three times and getting all heads is 0.5 x 0.5 x 0.5, which equals 0.125, or a 12.5% chance. Therefore, the correct answer to the question is option 4) 12.5.
Step-by-step explanation:
The probability of flipping a coin three times and having them all land "heads" up is calculated by multiplying the probability of flipping heads once by itself three times. Since there is a 50-50 chance that a coin will land on heads in a single flip, we calculate the probability of three heads in a row as follows:
- First flip: 0.5 (50% chance of heads)
- Second flip: 0.5 (50% chance of heads)
- Third flip: 0.5 (50% chance of heads)
Multiplying these together gives us:
0.5 x 0.5 x 0.5 = 0.125
Therefore, the probability of flipping the coin three times and getting all heads is 0.125, which can be expressed as 12.5% in terms of percentage. So, the correct answer is option 4) 12.5.
