I hope I helped you please mark me brainlist

Step-by-step EXPLANATION:

Solution :

Let A denotes Apples and O denotes ORANGES and it is given that there are 20 apples and 10 oranges.

Out of 20 apples 5 and 10 oranges 3 are defective.

P(AUB)=P(A)+P(B)−P(A∩B)

n(A)=(20C2)

P(A)=20C230C2

n(B)=22C2

P(B)=22C230C2

n(A∩B)=15C2

P(A∩B)=15C230C2

P(AUB)=20C230C2+22C230C2−15C230C2

P(AUB)=0.72
