Final answer:
The probability of getting tails in a weighted coin toss with a probability of heads equal to 3/4 is 1/4.
Step-by-step explanation:
To find the probability of getting tails in a weighted coin toss with a probability of heads equal to 3/4, we can subtract the probability of getting heads from 1. Since the probability of getting heads is 3/4, the probability of getting tails is 1 - 3/4 = 1/4. Therefore, the probability of getting tails is 1/4.
