The probability of parents passing on a particular trait to their child is 0.5.
To express this probability as a percent:
- 0.5 × 100 = 50%
To express this probability as a fraction:
- 0.5 = 1/2
To describe this probability, you can use the phrase "equal likelihood" or "50/50 chance."
So, for Part 1: P(passing on the trait) equals 50%.
