Can someone please help me.

At a quality control checkpoint on a manafacturing assembly line, 10% of the items failed check A, 12% failed check B, and 3% failed both checks A and B.

a. If a product failed check A, what is the probability that it also failed check B?

b. If a product failed check B, what is the probability that it also failed check A?

c. What is the probability that a product failed either check A or check B?

d. What is the probability that a product failed neither check A nor check B?
