is anyone able to help me with this question for my stats class? thanks

2. (7 points) In the Flying Squirrel Adventure Club, 40% of the members use walking sticks and 30% of members like to hike in the rain. 50% of members use walking sticks or like to hike in the rain (or both). For this question use "W" to represent "uses walking stick" and "R" to represent "likes to hike in the rain". (a) [3] Find the probability that a randomly chosen member of the club uses walking sticks and likes to hike in the rain. Hint: What is the formula for P(W or R)? What do you know? (b) [2] Are the events "uses walking sticks" and "likes to hike in the rain" independent? Why or why not? (c) [2] Are the events "uses walking sticks" and "likes to hike in the rain" mutually exclusive? Why or why not
