Suppose that currently 75% of women 25 through 49 years of age are participating in the labour force. Suppose that 78% of the women in that age group are married. Suppose also that 61% of all women 25 through 49 years of age are married and are participating in the labour force.

a. What is the probability that a randomly selected woman in that age group is married or is participating in the labour force?

b. What is the probability that a randomly selected woman in that age group is married or is participating in the labour force but not both?

c. What is the probability that a randomly selected woman in that age group is neither married nor participating in the labour force?

**Can you please show the formula used for parts b and c? Thank you
