I don’t know the first one but the second one is C
Answer:
3/26 students or 11%
Step-by-step explanation:
probability dependant formula:P(A∪B)=P(A)+P(B)−P(A∩B)
P(a)= basketball
P(b)=baseball
so
P(AUB)=P(A)+P(B)-P(A∩B)= 18/26+5/26-20/26=3/26
3/26 or 11%
OR you could solve this by adding all the sport/non sport #'s 18+5+6=29 and subtract 26 from 29
29-26=3
hence 3/26 students would randomly play basketball or baseball
Hope this Helps!
