In a fair coin toss, the probability of getting heads is 0.5. If a coin is tossed 40 times, we can expect the number of times heads will appear to be:
Expected heads = Total tosses × Probability of heads = 40 × 0.5 = 20
Therefore, the results should be heads approximately **20 times**.
The correct answer is **D. 20**.
Expected heads = Total tosses × Probability of heads = 40 × 0.5 = 20
Therefore, the results should be heads approximately **20 times**.
The correct answer is **D. 20**.
